Secure attachment

Attachment theory, developed by John Bowlby and extended by researchers including Mary Ainsworth and later Cindy Hazan and Phillip Shaver, describes the patterns people develop for how they relate to close others. These patterns — called attachment styles — are thought to form early in life through interactions with caregivers and continue to shape how adults behave in romantic relationships.

Secure attachment is the style in which a person feels comfortable depending on a partner and having a partner depend on them. Securely attached people generally find it relatively easy to get close to others, don't worry excessively about being abandoned or about a partner becoming too close, and can balance intimacy with independence without either feeling threatening. They tend to communicate needs directly, tolerate conflict without catastrophising, and recover from relationship ruptures well.

In the academic literature on adult romantic relationships, secure attachment is consistently associated with higher relationship satisfaction, better communication, and greater relationship stability. It is not a guarantee of a perfect relationship — every couple navigates challenges — but it is, by the evidence, the style most correlated with lasting, satisfying partnerships.

It is important to note that attachment styles exist on a spectrum and are not fixed destiny. Research suggests that experiences in adult relationships — including with a securely attached partner — can shift a person's attachment patterns over time. The framework is a useful lens for understanding relationship patterns, not a permanent label.

For compatibility-based matching, attachment style is one of many dimensions that can shape how well two people fit. Lamp matches on personality and values — the deeper signals of who you are and how you connect — which naturally encompasses the patterns that determine how you show up in a relationship.
