When Forever Stops Feeling Like Flourishing…

Monogamy, Positive Psychology and the Courage to Question the Life We Have Built

Most of us begin learning what a relationship is supposed to look like long before we have experienced one ourselves. Through our families, communities, culture, films, books, religion and the relationships we observe around us, we gradually absorb a familiar story about love. We are expected to meet somebody, fall in love, become exclusive, build a life together and, ideally, remain together for the rest of our lives. If we manage to do that, the relationship is often described as successful. If we separate, divorce, fall in love again or decide that the relationship no longer fits the people we have become, there can still be an uncomfortable assumption that something has gone wrong.

For many people, lifelong monogamy is exactly what they want, and it can be an enormously fulfilling way to live. There is something extraordinary about sharing decades with another human being, building a history together and becoming part of one another's story. Long-term relationships can offer security, companionship, intimacy, friendship, trust and a sense of belonging that develops slowly through years of ordinary and extraordinary experiences. There can be enormous beauty in having somebody beside you who remembers earlier versions of you, has witnessed your successes and failures, understands the experiences that have shaped you and knows the stories behind the person you have become.

There is also something deeply meaningful about continuing to choose somebody through different stages of life. The person you love at twenty-five may still be beside you at forty-five, sixty-five or eighty-five, having witnessed careers develop, children grow, illnesses occur, bereavements change the family and countless ordinary evenings unfold in between. There is nothing outdated or psychologically inferior about wanting that kind of commitment. In fact, for many people, the security and attachment created through a loving long-term relationship contribute significantly to their wellbeing.

However, there is another part of the conversation that deserves equal attention. What happens when the relationship survives, but the people within it stop flourishing? What happens when remaining together becomes the primary goal, regardless of the quality of the relationship being maintained? What happens when we become so attached to the idea of forever that we stop asking whether the life we are living still reflects our values, emotional needs and aspirations?

These questions do not attack monogamy. They simply ask us to distinguish between relationship structure and relationship quality. A relationship can be monogamous and deeply fulfilling, but it can also be monogamous and profoundly lonely. The fact that two people remain together tells us something about the duration of the relationship, but it does not necessarily tell us how each person experiences life within it.

Perhaps, therefore, we need a more sophisticated definition of what relationship success actually means. We frequently celebrate longevity in relationships. Twenty years, thirty years, forty years or a golden wedding anniversary can rightly be recognised as significant milestones. However, the number of years a couple has remained together tells us only one part of their story. It tells us that the relationship continued. It does not necessarily tell us whether those years contained affection, emotional safety, companionship, intimacy, curiosity, laughter, growth or happiness.

Two couples could both celebrate their thirtieth anniversary while living completely different emotional realities. One couple may still laugh together, enjoy each other's company, show affection, talk openly and support one another's individual growth. They may have experienced significant difficulties but developed ways of repairing conflict and rebuilding connection. Their relationship may look completely different from the one they had at twenty-five because they have deliberately allowed it to evolve with them.

Another couple may reach exactly the same anniversary while barely communicating beyond practical responsibilities. They may share a mortgage, household, children, friendship group and family traditions while having little emotional or physical intimacy. Neither person may describe the relationship as disastrous, yet neither may feel particularly alive within it. Both couples stayed together, but their experience of the relationship may be radically different.

This distinction is important because relationship persistence and relationship satisfaction are not identical psychological processes. Caryl Rusbult's Investment Model of Commitment proposed that commitment is influenced not only by how satisfied people are within a relationship, but also by the investments they have made and the perceived alternatives available to them. These investments can include time, emotional energy, shared possessions, friendship networks, children, finances and other resources that would be difficult or impossible to recover if the relationship ended (Rusbult, 1980).

This helps explain why someone can remain highly committed to a relationship while simultaneously questioning its quality. A person can love their partner, value the family they have created and feel deeply attached to the history they share while still recognising that important emotional needs are no longer being met. Commitment matters, but commitment alone should not automatically be interpreted as evidence of happiness.

Many of us inherit beliefs about relationships rather than consciously choosing them. We hear that relationships take work, that nobody is perfect, that marriage means staying through good times and bad, and that the grass is not always greener on the other side. We may also hear that people who separate have given up, while couples who remain together are praised for having made things work.

There is truth within many of these messages. Relationships do require effort, and human beings are imperfect. There will inevitably be periods when one partner is distracted, stressed, ill, exhausted or emotionally less available. There will be disagreements and disappointments. Sexual desire may fluctuate, life can become repetitive and external pressures can place enormous strain on even very secure couples. No meaningful long-term relationship can survive if every difficult period is automatically interpreted as evidence that the relationship should end.

However, respect for commitment can sometimes turn into fear of change. It can become an obligation to remain within a life because that life has existed for a long time. It can become the belief that because we once chose something, we are somehow required to continue choosing it regardless of who we become.

There is a significant psychological difference between saying, “I remain in this relationship because I genuinely continue to choose it,” and saying, “I remain in this relationship because leaving feels impossible.” The behaviours may look identical from the outside, but the internal experiences can be completely different.

A long-term relationship is rarely simply a romantic connection between two people. It becomes an entire ecosystem. There may be children, grandchildren, pets, homes, finances, pensions, mortgages, friendship groups and extended families that have become deeply intertwined. There may be holidays that have happened every year for decades, Christmas traditions that everyone expects to continue and routines that have become central to both people's sense of stability.

There is also identity. After many years together, people can stop being perceived entirely as individuals and become known as a couple. Their social world understands them as a unit and, over time, they may begin to understand themselves in the same way. Consequently, questioning the relationship can feel as though you are questioning an entire life rather than simply reconsidering a romantic partnership.

Somebody may wonder where they would live, whether they could afford to separate, what their children would think, whether friends would choose sides and whether they would ever find love again. They may imagine loneliness, financial instability or regret. They may also genuinely care about their partner and feel guilty that caring no longer seems sufficient.

These concerns should not be dismissed. They are real and significant. However, there is another side to the decision that deserves attention. We frequently ask ourselves what might happen if we change our lives, but we do not always ask what might happen if we do not. What happens if the relationship remains exactly as it is for another ten or twenty years? What happens if the same level of intimacy remains, the same conversations continue, the same frustrations repeat themselves and the same parts of ourselves remain unexplored?

Staying does not remove risk. Staying is also a decision, and every decision has consequences.

When people begin questioning long-term relationships, they often start by counting the years they have already invested. They may say that they have been together for twenty-five years, built everything together, raised children and survived difficult times. Those investments matter enormously. Rusbult's work helps explain why they strengthen commitment, because ending a relationship can involve losing resources, roles and identities that have become embedded within it.

However, respecting an investment does not mean allowing the past to determine every future decision. The twenty-five years already lived do not disappear if something changes. The Christmas mornings happened. The holidays happened. The children were raised. The laughter was real. The difficult periods survived together mattered. Love does not become meaningless simply because a relationship later changes form or comes to an end.

We sometimes treat endings as though they erase everything that came before them, but they do not. A chapter can have been deeply meaningful without needing to become the entire book. Instead of asking only how somebody could leave after everything they have invested, perhaps it is also useful to ask what kind of life they want to invest the next ten or twenty years in.

This becomes particularly important because human beings change significantly throughout adulthood. Think about the person you were twenty years ago. Your priorities may have been very different. Your confidence may have changed. Your career may have developed or completely altered direction. Your friendships may be different, your understanding of yourself may have deepened and your expectations of life may have evolved.

The way we understand relationships can change too. At twenty-five, excitement, attraction and building a future may dominate our thinking. At forty-five or fifty-five, emotional intelligence, communication, companionship, autonomy, shared values, sexuality, adventure and emotional safety may carry greater importance. The things we were prepared to compromise on at thirty may no longer feel negotiable at fifty.

This is not necessarily evidence of instability. It is often evidence of development.

Yet we sometimes expect relationships formed by our younger selves to operate according to decisions made decades earlier. Perhaps a more realistic expectation is that relationships should evolve because people evolve. The partnership required while raising young children may not be the relationship needed once those children become independent. The relationship that worked while two people were establishing careers may require significant adjustment when they reach midlife.

This does not automatically mean finding somebody else. Sometimes it means finding each other again. However, that can only happen if both people are willing to acknowledge that the relationship may need to change.

Long-term relationships also naturally become familiar. Familiarity can be comforting and psychologically important. You know how someone takes their coffee, which stories they will tell at dinner and what mood they are in by the way they walk into the room. You understand their routines, their habits and their history. That familiarity can create a powerful sense of security.

However, familiarity can also create complacency. We can gradually stop investigating somebody because we believe we already know everything about them. At the beginning of a relationship we are fascinated. We ask questions about childhood, dreams, fears, ambitions, travel, family, beliefs and the future. Years later, conversation can become dominated by logistics. We ask what time somebody will be home, whether the electricity bill has been paid, what is for dinner and who is taking the children somewhere.

Those conversations are unavoidable and necessary, but they should not become the entire relationship. It is possible to become an excellent household management team while slowly becoming emotional strangers.

Research into intimacy supports the importance of this emotional process. Laurenceau, Barrett and Pietromonaco (1998) found that intimacy develops through processes that include self-disclosure and perceived partner responsiveness. In simple terms, intimacy grows when we reveal meaningful parts of ourselves and experience the other person as understanding, validating and caring about what we have shared.

This helps explain why spending time together does not necessarily mean feeling connected. Two people can share a bed every night and still feel lonely. They can spend every evening in the same room while knowing very little about what is happening emotionally for each other. Physical proximity and psychological intimacy are not the same thing.

It can therefore be useful to ask whether your partner still knows what worries you, what excites you and what you want from the next stage of your life. Can you tell them when you are frightened? Can you talk openly about sex, loneliness, ambition or disappointment? Can you say that something is not working without fearing dismissal, anger or ridicule? Can your partner do the same with you?

Healthy intimacy requires expression, but it also requires responsiveness. It requires us to keep learning the person beside us rather than assuming that because we knew them twenty years ago, there is nothing left to discover. Your partner is not a book you finished reading decades ago. New chapters are being written all the time.

Positive psychology gives us another useful way of thinking about these questions. Rather than focusing exclusively on what is wrong or what causes distress, positive psychology also considers the conditions that allow individuals to function well and flourish. Martin Seligman's PERMA model describes five broad elements associated with wellbeing: Positive Emotion, Engagement, Relationships, Meaning and Accomplishment (Seligman, 2011).

Although PERMA was not designed specifically as a relationship assessment tool, it offers a useful framework for reflecting on the emotional quality of our relationships. Instead of asking whether a relationship is bad enough to justify changing it, we can ask whether it supports a life in which both people can flourish.

That is a very different question.

A relationship does not have to be catastrophic before it deserves attention. Nobody needs to have cheated, become abusive or created constant conflict before somebody is allowed to recognise that they are unhappy. Sometimes the problem is not the presence of something terrible. It is the gradual absence of something important.

There may be little affection, little intimacy, little laughter or little curiosity. There may be very little excitement about the future, limited personal growth and few emotionally meaningful conversations. Everything may continue functioning perfectly well at a practical level, but functioning and flourishing are not the same thing.

The first component of PERMA, positive emotion, gives us one way to think about the emotional climate of a relationship. Positive emotion does not mean expecting your partner to make you permanently happy, nor does it mean that healthy couples never experience anger, sadness, boredom or frustration. It means asking whether the relationship contains enough experiences of affection, warmth, amusement, gratitude, hope, interest and love.

Barbara Fredrickson's broaden-and-build theory proposes that positive emotions can broaden our patterns of thought and behaviour and, over time, help us build enduring psychological and social resources (Fredrickson, 2001). Within relationships, this gives greater significance to moments that might otherwise appear trivial.

The joke while cooking dinner matters. The affectionate message matters. The spontaneous kiss matters. The conversation that makes you laugh matters. The private humour nobody else understands matters. The feeling that your partner is genuinely pleased to see you matters. Relationships are rarely sustained by one enormous romantic gesture every few months. They are shaped through thousands of small interactions.

Gottman's research on couples has also highlighted the importance of the balance between positive and negative interactions, particularly during conflict. His work has often been summarised by the idea that stable and happier couples demonstrate substantially more positive than negative interactions during conflict. The familiar “five-to-one” ratio should not be treated as a rigid mathematical rule, but it illustrates the broader importance of maintaining a positive emotional climate within relationships (Gottman et al., 1998).

The issue is therefore not whether couples ever argue. They will. The more useful question is what surrounds those arguments. Is there affection, humour, kindness, respect and repair, or has criticism, contempt, withdrawal or indifference become the dominant emotional language of the relationship?

Engagement, another element of PERMA, is also important because one of the reasons early relationships often feel exciting is that they are filled with novelty. Everything is new. There is a first date, a first kiss, a first weekend away, a first holiday and a first Christmas. New experiences naturally generate attention and curiosity.

Long-term relationships inevitably contain more repetition, but repetition does not have to mean emotional stagnation. Research by Aron and colleagues (2000) found that couples who participated together in novel and arousing activities reported improvements in experienced relationship quality compared with couples engaging in more mundane activities.

This does not mean couples need to spend their lives jumping out of aeroplanes or travelling around the world. Novelty can be remarkably simple. It might involve trying a new restaurant, taking a class together, walking somewhere unfamiliar, cooking something different, going dancing, taking a spontaneous day trip or simply turning off the television and having a conversation that does not involve household administration.

Sometimes people assume that they need a new relationship when what they are actually craving is newness within their life. That distinction deserves careful thought.

The relationship element of PERMA is perhaps the most obvious, but being in a relationship does not automatically satisfy our need for connection. Self-Determination Theory, developed principally by Edward Deci and Richard Ryan, identifies autonomy, competence and relatedness as fundamental psychological needs (Deci & Ryan, 2000). Research applying these principles to romantic relationships has found that fulfilment of these psychological needs is associated with better personal and relationship wellbeing (Patrick et al., 2007).

This encourages us to look beyond simply having a partner and consider whether we actually feel connected to that person. Do we feel understood, valued and emotionally supported? Can we be vulnerable? Can we depend upon them? Are they interested in our internal world rather than simply the practical events of our day?

Autonomy is particularly important because healthy commitment should still contain a sense of choice. Autonomy does not mean behaving selfishly or independently of everyone else. It means experiencing our actions as genuinely chosen rather than controlled or coerced. Research by Knee and colleagues (2005) found that greater self-determination within romantic relationships was associated with less defensive responding during conflict and better relationship functioning.

There is therefore an enormous psychological difference between staying because you feel that you have no choice and staying because, knowing the relationship fully, you continue to want it. Perhaps one of the most meaningful ways to think about monogamy is not that two people once promised never to leave, but that two people continue to have agency and continue to choose one another.

Meaning is another important part of flourishing. Long-term relationships naturally accumulate enormous amounts of shared meaning through children, homes, photographs, holidays, bereavements, celebrations, private jokes and experiences that have shaped both people. That history matters, but relationships cannot survive indefinitely on historical meaning alone.

At some stage, couples also need to ask what they are creating now. What are they looking forward to? What do they want the next five or ten years to contain? What do they want retirement to look like? Where do they want to travel? What do they still want to learn, create or experience together?

This can become especially important during midlife, when children may become increasingly independent and careers or family responsibilities begin to change. Two people may suddenly realise that much of the shared project that organised their relationship has disappeared. That does not necessarily mean the relationship has reached the end. It may simply mean that a new shared project needs to be created.

Accomplishment and growth are also important because healthy relationships should ideally support both people in becoming more of who they are capable of becoming. One person may gain confidence, study, change careers, make new friends, become more independent or develop interests that did not exist when the relationship began.

Sometimes personal growth creates insecurity because change introduces uncertainty. A partner may say, “You have changed,” as though change itself is evidence that something has gone wrong. Yet after twenty or thirty years of life, we should expect to have changed.

Perhaps a more useful question is whether the relationship has enough flexibility to accommodate that development. Can each person become more of themselves within the relationship, or does maintaining the relationship require one or both people to become smaller versions of themselves?

Love requires compromise, but compromise should not routinely become self-erasure.

Positive psychology can also help us understand the importance of gratitude. Familiarity can make kindness almost invisible. Something that felt incredibly thoughtful during the first year of a relationship can become completely expected ten years later. Somebody may make coffee every morning, remember appointments, cook when the other person is tired or send a message to make sure they arrived somewhere safely. Initially those behaviours may feel deeply caring, but over time they can become so normal that we stop noticing them.

Research by Algoe, Gable and Maisel (2010) found that gratitude following thoughtful partner behaviour was associated with increased relationship connection and satisfaction. Gratitude will not fix every relationship problem, but deliberately noticing and expressing appreciation can strengthen positive connection.

It is important that gratitude is expressed rather than simply assumed. Saying that you noticed something, appreciated it or were proud of your partner can change the emotional atmosphere of a relationship. Human beings often assume that the people closest to them already know how much they are valued, but knowing something intellectually and experiencing it emotionally are not always the same thing.

We also need to become better at celebrating one another's happiness. Relationships are often judged by how well people support one another through difficult times, and that is undoubtedly important. However, research by Gable and colleagues (2004) demonstrated that the way partners respond when somebody shares good news also matters. Active and constructive responses to positive events are associated with greater relationship wellbeing.

If your partner arrives home excited about an achievement, there is a significant difference between briefly acknowledging it and becoming genuinely interested. Asking what happened, how they felt and what happens next communicates that their joy matters to you.

A good relationship should therefore be somewhere we can safely bring our pain, but it should also be somewhere we can safely bring our happiness.

Couples can also become trapped waiting for the relationship to feel different before behaving differently. They wait until they feel connected before arranging quality time, wait until they feel affectionate before initiating touch and wait until they feel excited before planning something interesting. Eventually they can wait for years.

Sometimes behaviour needs to change first. Couples can create opportunities for positive emotion deliberately. They can plan something to anticipate, go somewhere new, eat together without phones, walk, talk, flirt, touch, travel, play or simply create environments in which they are more likely to experience each other outside the usual routine.

This does not guarantee that a relationship will improve, but it gives connection an opportunity to happen.

However, positive psychology should never be confused with toxic positivity. It should not become another social pressure encouraging somebody to remain within a relationship that consistently undermines their wellbeing. Gratitude does not mean ignoring neglect. Optimism does not mean denying reality. Resilience does not mean tolerating anything indefinitely, and forgiveness does not mean abandoning boundaries.

Positive psychology is not about pretending everything is fine. It is about understanding the conditions that support meaningful and psychologically healthy lives. Sometimes it helps people recognise how much remains good in their relationship. Sometimes it encourages conversations that have been avoided for years. Sometimes couples reconnect, seek counselling or deliberately rebuild intimacy.

At other times, greater self-awareness may reveal that something fundamental is missing.

Psychology cannot make the decision to stay or leave for somebody, nor should it. Its value lies in helping us understand ourselves well enough to make more conscious choices.

One of the most common responses when somebody questions a long-term relationship is that the grass is not always greener on the other side. That is true and worth remembering. A new partner will eventually become familiar. They will have irritating habits, experience stress, make mistakes and occasionally disappoint us. The intensity of early romantic novelty does not remain at the same level forever.

An established relationship contains years of reality, while a new relationship or imagined future may still contain projection and possibility. Comparing those experiences directly is rarely fair.

Perhaps, however, the grass metaphor can be extended. The important question is not simply whether the grass might be greener somewhere else. It is whether both people are still watering the grass where they are.

Are both people communicating? Are both willing to repair? Are both trying to create connection? Are both interested in improving intimacy and supporting the other's growth? Relationships do not require perfectly equal effort every day, because life will inevitably mean that one person carries more at certain times. However, healthy relationships require reciprocity over time.

One person cannot create mutual intimacy alone. You cannot communicate for two people. You cannot manufacture another person's curiosity about you, and you cannot force somebody to invest in a future they no longer want.

Perhaps one of the most difficult situations occurs when nobody has done anything dramatically wrong. Your partner may be kind, dependable and a good person. There may have been no betrayal, explosive argument or obvious reason why the relationship should end, yet something still feels wrong.

This can create enormous guilt because we often believe we need to produce a sufficiently serious justification before we are allowed to question a relationship. We may tell ourselves that other people have it worse, that we should be grateful or that wanting something different is selfish.

However, another person does not need to become a villain before we are allowed to acknowledge our emotional reality. Sometimes two good people can create a relationship that no longer meets important psychological needs. Sometimes they can rebuild it, sometimes they can renegotiate it, and sometimes they may ultimately want different lives. There is no single correct answer, but remaining should not require pretending.

A useful reflective exercise is to imagine that nothing dramatically changes. The relationship does not suddenly become worse, but it does not magically become better either. It simply continues exactly as it is now. Imagine yourself ten years from today with the same level of affection, communication, intimacy, laughter, conflict, routine, freedom and shared purpose.

How does that imagined future feel?

The purpose of the exercise is not to diagnose whether a relationship should end. It is simply a way of shifting perspective. We spend enormous amounts of time asking what might happen if we change our lives and later regret it. Perhaps we should occasionally ask what might happen if we change nothing and regret that instead.

Maybe our definition of relationship success therefore needs to become broader. A successful relationship may certainly be one in which two people remain together throughout their lives. It may also be one in which two people recognise that they have become disconnected and courageously rebuild their intimacy. It could be a relationship in which old assumptions are renegotiated and a completely new relationship is created between the same people.

There may also be circumstances where two people recognise that their relationship has reached the end of its journey and decide to move forward separately while treating one another with dignity. The length of the relationship alone cannot tell us which of these outcomes represents success.

Perhaps success is better understood through the quality of the lives and relationships people create.

There is something profoundly meaningful about choosing one person, not because society tells you that you should and not simply because you made a commitment decades ago, but because after years of knowing that person you still see value in the life you create together.

Perhaps that is a psychologically healthier understanding of monogamy. Instead of believing that choosing someone once means the relationship should never be questioned again, perhaps commitment means continuing to create a relationship that both people genuinely want to choose.

That kind of relationship requires ongoing communication, emotional intelligence, vulnerability, curiosity, autonomy, affection, responsiveness and a willingness to repair what has been neglected. Most importantly, it requires participation from both people.

Perhaps we also need to move beyond the simple question of whether we still love somebody. Love can remain present even when a relationship no longer functions particularly well. It may be more useful to ask whether we still enjoy the person, respect them, feel respected by them and feel emotionally safe around them. We can consider whether we can be fully ourselves, whether we still laugh together, whether we talk about meaningful things and whether there is enough affection, intimacy and curiosity to keep the relationship alive.

We might ask whether we celebrate one another, support one another's ambitions and create new memories together. We can consider whether we are able to disagree safely and repair afterwards. We can ask whether we know what our partner wants from the next ten years and whether they understand what we want.

Ultimately, we may need to ask whether we are choosing the relationship because it still represents a meaningful life or maintaining it primarily because changing our lives feels frightening.

The answer may not arrive immediately, and that is appropriate. Major life questions deserve more than impulsive answers.

It is also important to remember that flourishing does not mean chasing constant happiness or excitement. Positive psychology does not suggest that we should abandon relationships whenever they become ordinary. A meaningful life contains difficulty, responsibility, sacrifice and uncertainty. Relationships will sometimes be boring. Partners will irritate each other. Sexual desire may fluctuate. There will be periods when work, health, children or grief take priority.

The question is not whether every day feels wonderful. It is whether the broader pattern of the relationship allows both people to experience connection, autonomy, meaning, positive emotion and growth, and whether both people are willing to respond when something important begins to disappear.

Wanting more from life does not necessarily mean wanting another person. Sometimes someone feels restless and assumes that their relationship must be the problem when what they are actually craving is adventure, learning, friendship, purpose, challenge, creativity, autonomy, travel, sexuality or greater connection with themselves.

Before assuming that the relationship needs replacing, it may therefore be worth asking whether parts of the individual have been neglected. No partner can realistically provide every source of meaning, stimulation and fulfilment another human being needs. Sometimes flourishing involves strengthening the relationship, sometimes it involves strengthening the individual within it, and often it requires both.

Our lives are finite, and recognising that does not need to be frightening. It can encourage us to become more intentional about how we spend our time, who we spend it with and what we continue tolerating simply because it has become familiar. We do not have unlimited decades to postpone meaningful conversations, silence uncomfortable questions or repeatedly tell ourselves that we will eventually address something that no longer feels right.

At forty, fifty or sixty, questioning whether the life we built at twenty-five still fits us does not necessarily mean we are experiencing some stereotypical midlife crisis. Sometimes questioning is simply part of psychological development. Sometimes discomfort is information. Sometimes becoming more self-aware changes what we value, what we need and what we are willing to tolerate.

Wanting more does not automatically mean being ungrateful for what we already have. It may mean we have recognised that we are still developing. We may want more meaning, more conversation, more affection, more adventure, more emotional honesty or greater freedom to explore who we are becoming. Wanting those things does not necessarily mean the relationship has failed. It may simply mean the relationship needs attention.

That is why the first question does not necessarily need to be whether we should stay or leave. That question can be too large, too emotional and too final to begin with. Perhaps a better place to start is by asking what flourishing would look like for us now, what flourishing might look like for our partner and whether those two lives can still be created together.

Those questions allow room for curiosity rather than immediate judgement. They encourage us to examine whether our needs can be expressed, whether the relationship can adapt and whether both people are willing to participate in creating something better.

Sometimes that conversation can bring people back towards each other. It can remind them why they originally chose one another. It can reveal years of unintentional neglect and reopen conversations about affection, intimacy, sexuality, ambitions, travel, meaning and the future. Couples may begin dating again, talking more honestly, laughing more, reconnecting physically and creating new experiences together.

In those situations, questioning the relationship does not destroy it. It may actually help save it.

Reflection can also lead somewhere more uncomfortable. Sometimes one person wants to rebuild while the other does not. Sometimes values and visions of the future have become fundamentally different. Sometimes one person has been trying to create connection for years while the other has gradually withdrawn.

That is painful information, but it is still information.

Positive psychology does not promise that every relationship can or should be repaired. Nor does it suggest that flourishing means endlessly chasing something better. It simply reminds us that wellbeing involves more than surviving our circumstances.

The question becomes less about whether a relationship looks successful from the outside and more about what it feels like to live inside it. Do you feel loved, valued and emotionally safe? Can you express what you need? Can you become more of yourself? Can your partner become more of themselves? Is there still mutual effort, curiosity and a sense of shared meaning? When something important is missing, are both people willing to respond?

A relationship should not require constant happiness. Life includes disappointment, illness, grief, stress and ordinary periods when nothing particularly exciting happens. Flourishing means that there is enough goodness within the wider relationship to make those difficult periods worth navigating. There is enough affection to soften conflict, enough respect to make honesty possible, enough autonomy to allow growth, enough security to make vulnerability safe and enough meaning to make the future feel worth creating.

Relationships do not need perfect people. They need people who remain psychologically present. They need people who are willing to listen, repair, ask difficult questions and acknowledge when something has changed.

There is enormous courage in that because carrying on is often easier than questioning anything. Routine is powerful. Human beings can adapt to emotional distance, reduced affection, limited conversation and lack of intimacy until those experiences begin to feel normal. Our ability to adapt helps us survive difficult circumstances, but it can also allow us to remain inside lives that no longer make us particularly happy.

This is why reflection matters. Not because every uncomfortable feeling means that something should end, but because discomfort can sometimes signal that something deserves attention.

Ignoring the signal does not necessarily make it disappear. Resentment can develop. Curiosity can disappear. Separate lives can become increasingly normal. People stop touching, stop asking questions and stop looking forward to spending time together. Eventually the relationship can become something that both people maintain but neither actively experiences.

Perhaps that is one of the risks of relationships organised primarily around longevity. We can become excellent at staying, but staying and living are not always the same thing.

Healthy commitment may therefore require us to remain curious about the difference. It requires enough courage to ask periodically whether the relationship is still emotionally alive rather than simply still present. Forever should not become an excuse to stop investing. If anything, longevity should make intentionality more important.

Knowing somebody for thirty years does not mean there is nothing left to discover. There may be an entirely different person developing beside you, with dreams they have never voiced, fears they have never explained and parts of themselves they abandoned because life became busy. There may also be parts of you waiting to re-emerge.

Perhaps this is where some of the most meaningful relationship conversations begin. Instead of asking what is wrong with us, we can ask who we are becoming. Instead of asking why things are not the way they used to be, we can ask what our relationship could become now.

Those questions create movement. They recognise that the purpose of a long-term relationship cannot simply be preserving earlier versions of two people who no longer exist. The people who originally fell in love have changed. The challenge is discovering whether the people they have become can continue choosing each other.

There is something hopeful about that idea because it removes the expectation that love should remain unchanged and replaces it with the possibility that love can develop. Relationships can become more emotionally intelligent, more intentional and more honest over time.

Sometimes flourishing will involve recommitment. Sometimes it will involve renegotiation, counselling or changing established routines. Sometimes it will involve rebuilding intimacy, creating greater independence or completely reimagining what the next chapter looks like. Occasionally, it may involve recognising that the relationship has reached the end of its journey.

None of those outcomes automatically represents success or failure. What matters is whether decisions are reached consciously, respectfully and honestly rather than through fear, habit or social expectation.

Perhaps this is where our traditional understanding of monogamy can become more psychologically sophisticated. Monogamy does not need to mean being trapped by a decision made decades ago. It can mean repeatedly renewing that decision. It can mean two autonomous people continuing to choose exclusivity because the relationship remains meaningful to them.

There is something incredibly powerful about knowing that somebody is not beside you because they have nowhere else to go. They are beside you because, despite having agency over their own life, they continue choosing a life with you.

That kind of commitment contains freedom rather than fear, respect rather than possession and growth rather than stagnation. Choice matters precisely because alternatives exist. We do not demonstrate love by having no possible life outside a relationship. We demonstrate it by deciding which life we want to build.

We cannot know exactly what the next ten or twenty years will bring. We cannot guarantee that any relationship will last forever. We cannot predict illness, loss, career changes, family pressures or the people we will become.

What we can do is remain present. We can keep talking, asking questions and noticing when something feels different. We can express gratitude while still acknowledging dissatisfaction. We can appreciate the life we have built without becoming frightened of examining it.

Wanting to flourish does not have to be an act of selfishness. Flourishing does not mean pursuing individual happiness regardless of the consequences for everyone else. It means attempting to create a life that contains meaning, connection, authenticity, growth and psychological wellbeing while respecting the people affected by our choices.

Perhaps that balance is part of adulthood. We may never achieve absolute certainty or perfect relationships, but we can take responsibility for the lives we continue choosing.

We might therefore stop measuring relationship success solely by whether two people manage to remain together and become more interested in the quality of the relationship they continue creating. We can ask whether they still see one another, listen to one another and support one another's development. We can ask whether they can laugh, be vulnerable, disagree safely, talk about what is missing and create new meaning together.

Those questions may ultimately tell us far more than the number of anniversaries celebrated.

The goal should not simply be to spend as many years as possible beside another person. It should be to make those years worth living. It should be to create a relationship in which both people remain psychologically alive, can love without disappearing, commit without surrendering every part of their autonomy and create security without eliminating growth or possibility.

We can honour our shared history without allowing history to become a prison. We can recognise that familiarity does not have to become complacency and that intimacy requires curiosity. We can accept that people will change and attempt to create relationships flexible enough to change with them.

Maybe that is the kind of forever worth aspiring to. Not a promise that nothing will ever change, but a willingness to keep discovering whether the changing people inside the relationship can continue finding their way towards one another.

Perhaps one of the most powerful expressions of long-term love is therefore not simply saying that we are still here. Physical presence is only part of the story. Perhaps it is being able to say that we still see the person beside us, still want to understand them, still care about who they are becoming and still want them to flourish.

It is being able to say that after everything we have experienced, everything we have learned and all the ways we have changed, we still freely choose this life together.

That is a very different version of forever.

It is not simply endurance. It is participation.

It is not habit. It is intention.

It is not ownership. It is choice.

It is not remaining together because life has become too complicated to change. It is two people continuing to create a relationship worth staying for.

Perhaps that is where monogamy and positive psychology meet most powerfully. Not in the belief that relationships must last forever at any cost, but in the belief that if we are going to give another human being years of our lives, and receive years of theirs in return, those years should contain more than survival.

They should contain connection, growth, meaning, affection, laughter, respect, autonomy, intimacy, curiosity and shared experiences. They should contain the freedom to change, the courage to speak honestly and the willingness to notice when something important needs attention.

Perhaps the most useful question we can continue asking each other is not simply whether we are still together, but whether we are still creating a life in which both of us can flourish.

Because maybe the goal is not simply to stay together forever.

Maybe the goal is to make forever something both people would still choose.
