Attachment styles refer to the way people behave in relationships with others, particularly when it comes to how they form and maintain emotional bonds. There are four primary attachment styles: secure, anxious, avoidant, and ambivalent. People with a secure attachment style tend to have positive and trusting relationships with others, while those with an anxious attachment style may worry a lot about being abandoned or rejected. Those with an avoidant attachment style may have difficulty forming close bonds with others, and may prefer to be alone or independent. And people with an ambivalent attachment style may have conflicting feelings about their relationships and may be unsure of how to behave in close relationships.
