Being able to name one's own predominant attachment style, and those of others with whom one interacts, provides guidance for how to be manage those relationships.
Adult attachment designates three main “attachment styles,” or manners in which people perceive and respond to intimacy in romantic relationships, which parallel those found in children: Secure, Anxious, and Avoidant.
Basically, secure people feel comfortable with intimacy and are usually warm and loving;
anxious people crave intimacy, are often preoccupied with their relationships, and tend to worry about their partner’s ability to love them back;
avoidant people equate intimacy with a loss of independence and constantly try to minimize closeness.
In addition, people with each of these attachment styles differ in: their view of intimacy and togetherness the way they deal with conflict their attitude toward sex their ability to communicate their wishes and needs their expectations from their partner and the relationship
