Relationships shift over time, and not every change means love is disappearing. Research on couples in both escalating and de-escalating relationships has identified specific behavioral patterns that distinguish a relationship that is maturing from one that is genuinely winding down. The tricky part is that some of the most alarming-feeling changes, like a drop in intensity or a partner pulling back during stress, can look identical to falling out of love while having entirely different causes. Understanding what the evidence actually points to can help you figure out what you’re dealing with.
What Changes When a Relationship Is Actually Declining
Researchers who study how relationships evolve over time have found a fairly consistent set of shifts that occur when a couple is moving apart rather than growing closer. In de-escalating relationships, partners perceive decreases in positivity (the warmth and cheerfulness directed at each other), assurances (verbal and behavioral signals of commitment), and shared tasks (the willingness to split daily responsibilities together).1Journal of Social and Personal Relationships. Linking Maintenance Strategies to Relationship Development and Disengagement: A Reconceptualization These are sometimes called “maintenance behaviors” because they’re the things people do, often without thinking about it, that keep a relationship feeling alive. When love is healthy, these behaviors tend to increase or hold steady. When it’s declining, they quietly thin out.
Physical affection is another measurable signal. A large cross-cultural study on romantic touch found that people who reported higher levels of love for their partners used a wider variety of affectionate touch, including holding hands, caressing, hugging, and other forms of physical closeness. Love predicted about 15 percent of the variation in how many types of touch partners engaged in, and the connection held across all three dimensions of love: intimacy, passion, and commitment.2PubMed Central. Love and affectionate touch toward romantic partners all over the world In plain terms, when someone loves their partner more, they tend to touch them in more ways and more often. A noticeable, sustained drop in physical affection can reflect a genuine change in feeling, though context matters: stress, illness, and mood all influence touch independently of love.
The key word is “sustained.” A bad week, a stressful project at work, or even a rough month does not constitute a pattern. What researchers track is the trajectory over time. A relationship that is de-escalating shows these declines persisting and deepening, not bouncing back after the stressor passes.
Normal Cooling Off vs. Actually Falling Out of Love
One of the biggest sources of anxiety in relationships is confusing the natural settling of early-stage intensity with a partner’s love disappearing. Research on what’s called the “disillusionment model” helps explain why this confusion is so common. During courtship, partners tend to idealize each other. Romantic feelings run high, both people are presenting their best selves, and the result is a period of heightened passion. Once the relationship matures and daily life sets in, that idealization naturally fades. Couples who progressed through courtship very quickly seem especially vulnerable to this drop, because the idealization was more intense to begin with.3Journal of Family Issues. Courtship Progression Rate and Declines in Expressed Affection Early in Marriage
This fading of the “honeymoon glow” is not falling out of love. It’s a predictable transition from one phase of a relationship to the next. The butterflies settle, the constant texting slows down, and your partner stops dropping everything to see you on a moment’s notice. These shifts feel alarming if you’re interpreting them through the lens of early-stage romance, but they don’t signal a loss of love. They signal the relationship moving from infatuation to something more stable.
Interestingly, a certain amount of idealization appears to be protective. A 13-year longitudinal study of married couples found that spouses who idealized each other as newlyweds were more in love initially and less likely to experience declines in love over time.4PubMed. Positive illusions in marital relationships: a 13-year longitudinal study Related research shows that these “positive illusions,” the tendency to see your partner in a slightly rosier light than an objective observer might, are linked to higher satisfaction, less conflict, and a lower risk of breaking up.5PubMed Central. Improving Relationships by Elevating Positive Illusion and the Underlying Psychological and Neural Mechanisms So a partner who still speaks warmly about you, gives you the benefit of the doubt in disagreements, or describes you proudly to friends is probably not falling out of love, even if the daily intensity has cooled. The concern starts when that positive bias disappears and gets replaced by criticism or indifference.
Signs People Commonly Misread
Before assuming the worst, it’s worth considering how many common relationship dynamics look like fading love but aren’t. Attachment style is one of the biggest confounders. People with avoidant attachment tendencies naturally pull back when a relationship gets closer. They may become less communicative, resist deep emotional conversations, or seem to withdraw right when things are going well. This pattern is not about losing love; it’s about a deeply rooted discomfort with intimacy that often predates you entirely.
Research on closeness and distance in dating relationships shows that conflicts over how much togetherness each partner wants are extremely common, and they’re driven heavily by each partner’s attachment style. Avoidantly attached individuals, particularly men, are more likely to create distance. These recurring push-pull dynamics are linked to lower satisfaction but not necessarily to declining love.6SAGE Journals (Journal of Social and Personal Relationships). Issues of Closeness and Distance in Dating Relationships: Effects of Sex and Attachment Style If your boyfriend has always been somewhat independent or has cycled between warmth and withdrawal, the pattern you’re noticing may be more about who he is than how he feels about you.
Stress is another major factor. Attachment research shows that when people with insecure attachment orientations encounter chronic or acute stress, they respond with distinctive patterns of emotion regulation that can look a lot like falling out of love. Anxiously attached partners may become clingy or demanding under stress, while avoidantly attached partners tend to shut down emotionally and distance themselves.7PubMed Central. Adult attachment, stress, and romantic relationships If your boyfriend recently started a demanding job, is dealing with family problems, or is under financial pressure, emotional withdrawal may be a stress response rather than a love response. The distinguishing question is whether the withdrawal is generalized (he’s also pulling back from friends, hobbies, and family) or targeted specifically at you.
Health Issues That Mimic Emotional Withdrawal
This is one of those areas that almost never comes up in relationship advice but genuinely matters. Changes in physical health can mimic the symptoms of falling out of love so closely that both partners may misidentify the problem. A clear example is thyroid dysfunction. Both hypothyroidism and hyperthyroidism can impair libido in men and women. The mechanisms involve disruptions to sex hormone levels, as well as downstream effects on mood and energy that can look like emotional disengagement. Research on thyroid disease and sexual function found that correcting the thyroid condition led to dramatic resolution of sexual dysfunction in both men and women.8Sexual Medicine Reviews. The Impact of Thyroid Disease on Sexual Dysfunction in Men and Women
Depression works similarly. A person who is developing depression may lose interest in sex, stop initiating plans, seem emotionally flat, and have less energy for the relationship. From the outside, this is nearly indistinguishable from someone checking out of a relationship. The difference is that depression tends to blunt interest in everything, not just the partner. Sleep changes, appetite shifts, and loss of interest in previously enjoyed activities are clues that the issue is medical rather than romantic.
Medication side effects, particularly from antidepressants, blood pressure medications, and hormonal treatments, can also reduce libido and emotional expressiveness. If your boyfriend recently started or changed a medication and you’ve noticed a shift, the medication is worth considering before concluding that his feelings have changed.
How Communication Shifts Can Signal Trouble
Communication is where many people first notice something feels off, and research confirms that changes in how partners share with each other are meaningfully tied to relationship health. In relationships that are growing, partners perceive increasing openness and assurances over time. In relationships that are declining, the maintenance behaviors around positive communication and shared tasks drop off.9Journal of Social and Personal Relationships. Linking Maintenance Strategies to Relationship Development and Disengagement: A Reconceptualization
One area worth paying attention to is where the communication is happening. Studies on disclosure in relationships found that the medium matters. Greater self-disclosure done face-to-face was associated with higher relationship intimacy and satisfaction. But the same kind of sharing done through online channels was actually linked to lower intimacy and satisfaction, both for the person sharing and for their partner.10PLoS One. Effects of self- and partner’s online disclosure on relationship intimacy and satisfaction If your boyfriend has shifted from talking to you in person to communicating mostly through texts and social media, the relationship may feel less intimate even if the volume of contact hasn’t changed. This doesn’t necessarily mean he’s falling out of love, but it is a pattern that erodes closeness over time if it goes unaddressed.
Specific communication red flags that research consistently links to relationship decline include a drop in verbal affirmations (saying “I love you,” complimenting you, expressing appreciation), avoidance of conversations about the future, and a shift from “we” language to “I” language. These aren’t things to track obsessively on a daily basis, but a shift in the overall tone over weeks or months can be meaningful.
What Commitment Actually Depends On
When people ask whether their partner is falling out of love, what they’re often really asking is whether their partner is losing commitment. Love and commitment are related but not identical, and understanding what feeds commitment can clarify what’s going on. Researchers have identified several key factors that predict how committed someone feels to a relationship: how satisfied they are, how attractive their alternatives seem, how much they’ve invested in the relationship, their shared plans for the future, and social expectations from friends and family.11Social and Personality Psychology Compass. Relationship commitment regulation: Influencing a partner’s commitment to achieve one’s commitment goals
This framework is useful because it highlights that commitment can weaken for reasons that have nothing to do with you specifically. If your boyfriend suddenly has more appealing social options, if he’s reassessing what he’s invested, or if his friend group has shifted toward being single and dating around, his commitment level may fluctuate without his underlying feelings about you necessarily changing. Conversely, someone can love you deeply and still feel ambivalent about commitment if they’re uncertain about the future or feel that social norms point away from settling down.
The practical takeaway is that a partner who seems less committed isn’t always a partner who loves you less. Sometimes they’re a partner who is recalibrating their life goals, feeling pressure from outside the relationship, or struggling with the decision-making aspect of commitment itself. The concerning version is when multiple factors shift at once: lower satisfaction, increased interest in alternatives, withdrawal from shared plans, and reduced investment in the relationship. That pattern taken together is a stronger signal than any single behavior.
What You Can Actually Do About It
If you’re reading this, you’re probably past the point of wanting to diagnose the problem and into the territory of wanting to fix it. Research offers some concrete guidance here. One of the strongest evidence-based approaches is doing novel and challenging activities together. The logic comes from self-expansion theory: when a relationship is new, simply being with your partner is novel enough to fuel excitement. As the relationship matures and you’ve absorbed each other into your daily routines, that built-in novelty disappears, and the relationship can feel stale. Deliberately introducing new, challenging shared experiences, whether that’s travel, a new hobby, or even something as simple as exploring an unfamiliar part of town, can re-associate the excitement of novelty with the relationship itself.12PubMed Central. Self-Expansion Activities with a Partner as One Path to Well-Being
This isn’t about grand romantic gestures. It’s about breaking routines that have made the relationship feel predictable. Couples who fall into a pattern of the same restaurants, the same Friday-night routine, and the same conversations are more prone to the kind of boredom that masquerades as falling out of love. The research suggests that it’s the novelty and challenge of the activity that matters, not its cost or scale.
For deeper issues, particularly when communication has broken down or conflict has become entrenched, couples therapy with an evidence-based approach can make a significant difference. Emotionally Focused Therapy, which is rooted in attachment theory, has been shown to help couples even when stress levels are high, and has demonstrated effects on reducing depressive symptoms and helping partners regulate their stress responses in the context of the relationship.13PubMed. Creating relationships that foster resilience in Emotionally Focused Therapy The goal is to identify the negative interaction cycles that both partners have fallen into, often without realizing it, and restructure them so that both people feel more emotionally secure.
Bringing up therapy can feel like admitting the relationship is in trouble, but the research framing is worth keeping in mind: therapy works best when it’s used before the relationship has deteriorated to a crisis point, not after. If you’ve noticed the patterns described earlier and they’ve been persistent, raising the idea sooner gives it a better chance of helping.
When It’s Worth Having the Conversation Directly
At some point, reading signs and analyzing behavior reaches its natural limit, and the most useful thing you can do is talk to your boyfriend about what you’re noticing. This is harder than it sounds, partly because the question “are you falling out of love with me” puts most people on the defensive and rarely produces an honest answer in the moment. A more productive approach is to describe the specific changes you’ve observed without assigning them a meaning. “I’ve noticed we don’t spend as much time together as we used to” or “I feel like we’ve been more distant lately” invites a conversation. “Are you still in love with me?” invites either reassurance or panic, neither of which is particularly informative.
The research on disclosure is relevant here. Self-disclosure done in person is associated with greater intimacy and satisfaction, while the same kind of openness expressed online tends to have the opposite effect.14PLoS One. Effects of self- and partner’s online disclosure on relationship intimacy and satisfaction So have the conversation face-to-face, not over text. The emotional cues you pick up in person, tone of voice, eye contact, body language, are part of what makes the conversation productive.
Pay attention to how he responds. A partner who is going through a rough patch but still loves you will typically engage with your concern, even if clumsily. They may not have a perfect answer, but they’ll show signs of caring that you’re worried. A partner who has genuinely checked out tends to respond with dismissiveness, irritation at being asked, or a flat reassurance that doesn’t match their behavior. The response itself is data.
Your Own Anxiety as a Variable
It’s worth asking yourself honestly whether you’ve always been prone to this kind of worry. People with anxious attachment orientations are particularly sensitive to perceived changes in closeness. Research shows that anxiously attached individuals are hypervigilant about signs of rejection and tend to interpret ambiguous partner behavior in the most threatening way possible. A partner who is tired, distracted, or having a bad day can trigger a cascade of worry that feels completely real and proportional in the moment but is actually being amplified by your own attachment system.
This doesn’t mean your concerns aren’t valid. But if you find yourself cycling through this worry repeatedly, in this relationship and in past ones, the pattern may have as much to do with your own relationship wiring as with your boyfriend’s actual feelings. Closeness-distance conflicts are especially common when one partner is anxiously attached and the other leans avoidant, creating a cycle where one person pursues and the other withdraws, which prompts more pursuit, which prompts more withdrawal.15SAGE Journals (Journal of Social and Personal Relationships). Issues of Closeness and Distance in Dating Relationships: Effects of Sex and Attachment Style Recognizing this pattern, if it applies to you, is one of the most genuinely useful things you can do, because it shifts the question from “is he falling out of love” to “are we stuck in a cycle that makes it feel that way?”
Individual therapy can be as valuable as couples therapy in this situation, because understanding your own attachment patterns changes how you interpret your partner’s behavior. When you stop reading every quiet evening as evidence of declining love, you create space for the relationship to breathe, and you get better at distinguishing genuine red flags from background noise.
