Approximately 55% of adults function according to a secure attachment style, according to Cindy Hazan and Phillip Shaver, who adapted attachment theory to adult relationships in 1987. Scientific resources on this subject are gathered in our thematic dossier Attachment. This figure may be surprising in a culture that values stories of romantic suffering—but the majority of adults manage to maintain intimate relationships with relative ease.
Secure attachment does not resemble what romantic culture presents to us as the ideal: no intense fusion, no all-consuming passion, no total dependence on the other person. It is something more discreet and, ultimately, more solid: a way of relating that allows for both closeness and autonomy, intimacy and freedom.
Here are 10 concrete signs that characterize this style:
- Comfortable with closeness AND autonomy
- Communicates their needs directly
- Is not afraid of conflict
- Trusts without losing themselves
- Temporary separation does not cause anxiety
- Does not try to test their partner
- Has a positive view of themselves AND others
- Responds to the other person’s emotional needs without erasing themselves
- Can end a relationship that is not right for them
- Benefits from a diverse support network
Here is a detailed look at each of these signs, along with the associated scientific foundations:
1. You are comfortable with closeness AND autonomy. A secure person does not experience intimacy as a threat to their identity, nor their partner’s autonomy as rejection. They can be fully present in a relationship while having their own interests, friends, and projects. When their partner needs space, they interpret it as information about their needs—not as a sign of disinterest. This dual comfort—with closeness AND distance—is precisely what Hazan and Shaver identified as the central marker of the secure style. Insecure styles, by contrast, are uncomfortable at one end or the other of the spectrum: too much distance—that is the anxious attachment style—or too much closeness (avoidant style).
2. You communicate your needs directly. This skill lies at the heart of communication between couples as described by Gottman’s research. Instead of pretending that everything is fine when it is not, or hoping that their partner will guess, a secure person expresses their needs clearly. “I need more time alone this week” or “I would feel better if you let me know when you are coming home late”—direct requests, without dramatization or minimization. This ability stems from positive internal working models: a representation of oneself as someone whose needs deserve to be heard, and a representation of the other person as someone generally able and willing to respond to those needs.
3. Conflict does not frighten you. Disagreement is not perceived as a threat to the relationship. A secure person can maintain a viewpoint that differs from their partner’s without fearing that it will end the relationship. They can also hear criticism without falling apart or immediately counterattacking. Gottman showed that couples with a high positive-to-negative ratio (at least 5 positive interactions for every 1 negative interaction) move through conflict without allowing it to erode their bond. This ratio is not a conscious calculation—it is the by-product of a way of being together in which concern for the other person’s well-being is taken for granted.
4. You trust without losing yourself. Trust is not a naïve decision for a secure person—it is based on observing their partner’s actual behavior. And this trust does not erase judgment: if repeated behaviors indicate unreliability, a secure person can recognize it and draw the appropriate conclusions, without catastrophizing or denial. When trust is broken by a more serious hurt, the question of forgiveness arises differently: our scientific guide to forgiveness in couples explores what research shows about this complex process.
“Trusting without losing yourself” also means maintaining an identity of your own within the relationship. Secure people do not disappear into their partner—they remain themselves while fully committing.
5. Temporary separation does not cause you anxiety. A partner’s business trip, an evening out with friends, a few hours without news—these situations are experienced neutrally or even positively (time for oneself, personal activities). The alarm system is not activated by normal, predictable absences. This regulation of separation anxiety is directly linked to what Bowlby called the “secure base”: the internal representation of a bond strong enough to tolerate temporary distance. A secure person carries this base with them—they do not need constant confirmation of the other person’s physical presence. This is the opposite of anxious functioning, characterized by an alarm that is activated by the slightest absence.
6. You do not try to test your partner. “Testing” behaviors—pretending to be unavailable to see if the other person worries, provoking scenes to gauge attachment, withdrawing to check whether the other person comes back—are characteristic of insecure styles. A secure person does not need them: they trust without having to create crisis situations to confirm it.
Security in attachment is not the absence of a need to be loved—it is the confidence that this need can be expressed without destabilizing the relationship.
— John Bowlby, A Secure Base, 19887. You have a positive view of yourself AND others. Researchers Bartholomew and Horowitz (1991) proposed a two-dimensional model for classifying attachment styles: the view of oneself (positive or negative) and the view of others (positive or negative). The secure style corresponds to a positive view of both: “I am a person of worth” AND “Other people are generally caring and reliable.” This dual positivity is not naïveté—it is a basic disposition that can be revised through experience. A secure person can recognize that a specific partner is unreliable without concluding that “all men are the same” or “no one is worth loving.” To understand how this model relates to insecure styles, our guide to marital satisfaction offers a comparative perspective.
8. You respond to the other person’s emotional needs without erasing yourself. A secure person is capable of empathy and support without dissolving into the other person’s distress. If their partner is going through a difficult period, they can be present and offer support without feeling overwhelmed or, conversely, without becoming emotionally disengaged. This ability—which researchers call “sensitivity” in the parenting context—is also linked to mentalization: understanding that the other person has an inner life distinct from one’s own, with needs of their own that are not implicit demands for abandonment or fusion.
9. You can end a relationship that is not right for you. Perhaps the least obvious sign, but one of the most characteristic, and it overlaps with the profiles described in John Alan Lee’s love styles: a secure person can recognize when a relationship is not right for them and end it, even if they are attached to it. They do not stay out of fear of being alone, excessive guilt, or because they do not believe they can find anything better. The ability to leave mirrors the ability to stay: both require a fundamental confidence in one’s own worth and in the possibility of future connection.
10. You benefit from a diverse support network. Secure people do not place all their relational needs in a single relationship. They have close friends, nurturing family relationships, and sometimes communities to which they belong. This diversity is not a way of avoiding commitment to their primary relationship—it is what protects it from overload. Cacioppo (2008) showed that the quality of the overall social environment—not only the romantic relationship—is a powerful predictor of psychological and physical well-being. Secure people naturally build this environment. This openness to varied connections is echoed in research on intercultural exchanges documented by LLL Russia magazine in the field of relational well-being.
What if I only recognize myself in a few of these signs?
Attachment security is a continuum, not a closed category. It is entirely possible to recognize yourself in 5 or 6 of these signs, and less so in others—depending on areas of life, specific partners, or the periods you are going through.
The concept of earned secure attachment (earned security), developed by Mary Main, is particularly important here: adults who had difficult childhoods can develop, through corrective relational experiences and sometimes therapy, a way of relating equivalent to the secure style. It is not the same as original secure attachment—there is often some residual vulnerability, a memory of the past—but functionally, it produces the same patterns.
What these 10 signs describe is not an unattainable ideal. It is a way of relating that many people cultivate gradually, with awareness, effort, and often with the help of relationships that have taught them—sometimes for the first time—that being fully oneself and fully connected are two things that go together.
