Rekindling love in a fading relationship: what attachment science really says
This article is based on a review of the scientific literature in attachment psychology and couple therapy, as well as on my academic research on the flexibility of dyadic sexual scripts.
"We don't feel much anymore." "We love each other, but the flame has gone out." "Can we fall in love with the same person again?" These phrases come up constantly in therapy, and they reflect a legitimate concern: watching a relationship fade away without knowing if the process is reversible. The good news is that research over the last few decades has mapped the mechanisms of romantic attachment quite precisely—and shown that they are malleable . Lasting love isn't a matter of luck; it's a system maintained by identifiable micro-behaviors, many of which can be deliberately reactivated. This article reviews what science is actually establishing about attachment triggers—carefully distinguishing well-documented mechanisms from popular myths.
Lasting love is not a state one endures; it's a system one cultivates. What has faded through neglect can often be rekindled through care.
Is love a chemistry that inevitably runs out?
This is the most discouraging belief—and it's partly false. It's true that the initial passionate phase relies on a particular neurochemistry: budding love activates the dopaminergic reward circuits, the same ones involved in addictions, which explains its obsessive and euphoric nature. This intensity doesn't last—the brain returns to its equilibrium, and that's a good thing, because no one could function in that state for long.
But the idea that "love inevitably dies" conflates the end of blind passion with the end of love itself. Research has long distinguished between passionate love and companionate love , supported in particular by oxytocin and vasopressin, the neuropeptides of lasting bonds. And above all, the imaging work of Acevedo and Aron (2012) has shown that some long-term couples continue to activate the reward circuits of romantic love—without the obsessive anxiety of the early days. In other words: serene, long-term passion exists, it is documented in the brain, and it is not a product of chance. What distinguishes the couples who maintain it is not luck, but what they do—which is precisely the subject of what follows.
How do you react when your partner tells you good news?
Here's one of the strongest—and most overlooked—predictors of a couple's stability. Psychology has long held that couples are judged by how they weather adversity. Shelly Gable's research on capitalization overturned this idea: how we react to each other's good news predicts intimacy and longevity at least as well as how we handle conflict.
When your partner shares a success or a joy, your response falls into one of four styles, and only one truly builds the bond:
Active and constructive : you stop, you turn towards the other person, you show genuine enthusiasm and you ask questions to prolong the moment ("That's great, tell me how it went!"). This is the only style that fosters intimacy.
Passive and constructive : you give a lukewarm nod of approval without looking up ("Ah, great," and you return to your screen). The other person senses that their joy has not been shared.
Active and destructive : you immediately point out the risks ("A promotion? You'll be working even more hours, we won't see each other anymore"). You break the momentum.
Passive and destructive : you ignore the news or you steer the conversation back to yourself. The other person feels invisible.
Clinical teaching is liberating because it's accessible to everyone: the active-constructive response requires little effort for a major benefit. If you were to change only one thing in your relationship this week, it would probably be this.
What "responding with presence" means, and why it's different for everyone
At the heart of emotional security lies a concept researchers call perceived partner responsiveness : the feeling of being understood, validated, and taken seriously by the other person. It is one of the most well-established pillars of the psychology of intimate relationships, associated with marital satisfaction as well as sexual desire, regardless of gender or sexual orientation.
A very common obstacle undermines this process: the confusion between listening and solving . Faced with the other person's distress, many people—often, but not exclusively, with a "fixing" mindset—immediately offer solutions, whereas the other person was primarily seeking to feel heard. The logical solution, offered too soon, is perceived as invalidation: one person feels misunderstood, the other feels rejected in their effort to help. Learning to validate before solving ("I understand that this is difficult," before offering any advice) is one of the most transformative skills developed in couples therapy. In the age of the phone, this also involves a very concrete factor: phubbing —checking one's screen while the other person is speaking—is experienced as a direct attack on this responsiveness and erodes the connection through small, repeated steps.
Can love be rekindled intentionally? Three counterintuitive mechanisms
This is the question that most often brings people to consultation: when the feeling has faded, can it be revived by an act of will? Research describes several levers, three of which are particularly counterintuitive.
Breaking free from routine together (self-expansion). Arthur Aron's self-expansion model posits that passion thrives on novelty and growth: initially, we expand through contact with the other, we discover, we learn. When predictability sets in, desire declines—not through a loss of feeling, but through a halt in expansion. Aron's studies show that couples who regularly share new and stimulating activities report a higher quality of relationship. Rekindling desire comes less from repeated romantic dinners (which don't change one's inner state) than from the shared exploration of the unknown, which allows us to rediscover each other in a new light.
Mistaking adrenaline for desire (the misattribution of arousal). The famous Capilano Bridge experiment (Dutton & Aron, 1974) showed that the brain misattributes the source of intense physiological arousal: a fast-beating heart in a context of fear or exertion can be reinterpreted as attraction to the person present. A practical application: activities that activate the nervous system and are shared (sports, shared challenges, thrills) can rekindle feelings of desire much more effectively than a calm and routine setting. This should be handled with care, but the mechanism is real.
Asking rather than giving (the Benjamin Franklin effect). This is the most paradoxical. When a partner has distanced themselves, the other's reflex is often to shower them with gifts and attention—which frequently produces the opposite of the desired effect, creating pressure and guilt. Social psychology suggests the opposite approach: requesting a service, help, or expertise from the distant partner. By doing the favor, their brain resolves the dissonance between their action and their detachment by readjusting their attitude ("if I'm doing this for this person, it's because I care"). Giving the other person the space to invest concretely can reactivate their attachment—where over-giving extinguished it .
Sculpting the other towards their best self: the Michelangelo phenomenon
Of all the mechanisms for lasting love, one is particularly beautiful—and solidly established by the work of Caryl Rusbult and his colleagues. The Michelangelo phenomenon stems from an image: just as the sculptor said he was only liberating the figure already present in the block of marble, partners have the power to "sculpt" the other toward their ideal self —the person they aspire to become.
The mechanism unfolds in three stages: the partner perceives the other's potential and aspirations (sometimes more clearly than the other person themselves), behaves in a way that encourages the emergence of these qualities, and the other person effectively progresses toward their ideal. Research links this process to greater personal and marital satisfaction, and to a longer-lasting relationship. Conversely, a partner who—even unintentionally—confines the other within their limitations or discourages their aspirations inhibits this growth. The clinical question I often ask is: are you cementing your partner in their flaws, or are you sculpting them toward their dreams?
Beware of myths: what science doesn't say
While some mechanisms are solid, the field of "love" carries with it preconceived ideas that need to be defused.
The myth of "playing indifference".
The idea that you have to make yourself desirable by becoming cold and distant is false. Walster's work (1973) nuanced this: a person who is cold to everyone is perceived negatively, and a person who is available to everyone loses perceived value. What attracts is selective availability —being warm and receptive to your partner while maintaining your own boundaries, ambitions, and life with the rest of the world. In short: the solution to "being taken for granted" is never to become cold to your partner, but to stop being so readily available to others.
The myth of attractive perfection.
Contrary to popular belief, infallibility creates distance. The Pratfall effect shows that a minor clumsiness or an acknowledged vulnerability makes a competent person more endearing, not less so. A partner who is always rational, always "right," arouses resentment; one who dares to show a flaw invites empathy. Vulnerability is not the enemy of attachment: it is a prerequisite.
Caution regarding "differences between men and women".
Much of the popular literature on attachment overinterprets gender differences based on neurobiology (oxytocin "feminine," vasopressin "masculine") or evolutionary psychology. These average differences sometimes exist in studies, but they are small, highly overlapping (the male and female distributions largely overlap), strongly influenced by culture, and not predictive at the individual level. Clinically, it is far more useful to understand the specific dynamics of your relationship than to apply gender generalizations. Notably, the demand-withdrawal cycle, long described as "the woman demands, the man withdraws," is actually observed in same-sex couples and depends on the position (the one who wants change makes the demand, the one who maintains the status quo withdraws), not on biological sex.
The common thread: flexibility rather than intensification
One pattern runs through all these mechanisms. What rekindles a relationship is never doing more of the same—more gifts, more demands, more reproaches, more identical dinners. It's doing things differently : changing the tone of response (building on existing relationships), validating instead of resolving, introducing novelty, asking instead of giving, encouraging each other's growth. In other words, reactivating love is a matter of flexibility —the couple's ability to revise their relationship patterns when they no longer produce a connection.
This is precisely what research on script flexibility establishes in the realm of intimacy: couples able to adjust their scripts (cognitive, emotional, behavioral, and communicational) maintain higher levels of satisfaction, and this flexibility benefits both partners (Bouchard et al., 2023). Lasting love is not love that never changes—it is love that knows how to adapt.
Conclusion: love is cultivated, it is not something that is endured.
Attachment science paints a message that is both demanding and profoundly optimistic: lasting love is not a neurochemical lottery in which we are passive spectators. It is a living system, sustained or eroded by specific behaviors—the way we welcome each other's joy, listen to each other's distress, introduce new experiences, and encourage each other's dreams. A couple that fades away is not necessarily a couple that dies: it is often a couple that has stopped performing these actions, and that can relearn how to do so.
However, be careful not to confuse the rekindling of a love dulled by time with clinging to a relationship that has become destructive: these are two different situations, and distinguishing between them is part of the therapeutic process. But when the attachment remains intact beneath the dust of daily life, the science is clear: it can be revived. Not by loving each other "more," but by loving each other differently .
