Relationship anxiety is persistent worry, fear or insecurity that is specifically triggered by close relationships.
It can affect people who are in a relationship, people who want to be in one, and people who have ended relationships but find the anxiety following them into each new connection. It is one of the most common and most misunderstood forms of anxiety, because it is so often mistaken for a problem with the relationship itself rather than recognised as an anxiety condition that the individual carries.

Relationship anxiety typically involves a deep, underlying fear of losing the relationship, being rejected or abandoned, not being good enough for a partner, or being hurt in the way that past relationships or experiences have caused pain. These fears drive a range of behaviours that are damaging to both the individual and to the relationship itself: constant reassurance-seeking, jealousy, controlling behaviours, pushing partners away, or the opposite, becoming so dependent on the relationship that the person loses their sense of identity.

Relationship anxiety is strongly linked to attachment patterns formed in early life. The way our earliest relationships taught us to expect love, consistency and safety from others shapes the way we relate to partners in adulthood. People with anxious attachment styles live in constant anticipation of being let down, abandoned or rejected, even in secure and loving relationships. People with avoidant attachment styles fear intimacy and vulnerability and protect themselves by keeping emotional distance, often without understanding why.

Left unaddressed, relationship anxiety damages relationships that would otherwise thrive, creates cycles of self-sabotage, and can lead to a pattern of repeated relational pain across a lifetime. With the right treatment, the underlying anxiety can be fully resolved and relationships can become a source of genuine security, joy and connection rather than a source of constant threat.
