I recently found this online survey, and consider the results very enlightening: Attachment Style Here's another page on attachment theory, explaining three kinds of attachment one can have with one's parents and subsequently with romantic partners: Great Ideas in Personality--Attachment Theory excerpt: Secure adults find it relatively easy to get close to others and are comfortable depending on others and having others depend on them. Secure adults don't often worry about being abandoned or about someone getting too close to them. Avoidant adults are somewhat uncomfortable being close to others; they find it difficult to trust others completely, difficult to allow themselves to depend on others. Avoidant adults are nervous when anyone gets too close, and often, love partners want them to be more intimate than they feel comfortable being. Anxious / ambivalent adults find that others are reluctant to get as close as they would like. Anxious / ambivalent adults often worry that their partner doesn't really love them or won't want to stay with them. Anxious / ambivalent adults want to merge completely with another person, and this desire sometimes scares people away.
