Attachment styles are patterns of intimacy developed in our formative years that may have an impact on future relationships. Di shares with Alex the model developed by Stan Tatkin to simplify attachment theory using the metaphor of waves, islands and anchors, from his book, "Wired for Love." Waves have an up and down style where they want to be close but push people away; the Island likes to have alone time and their own space whilst anchors have a nice balance of both waves and islands. The aim is to be more like an anchor and understand your own and your partners' attachment styles to reduce the conflict in the relationship.
