Attachment therapy is based on attachment theory and explores how one’s early childhood or formative and developmental experiences might impact one's ability to form meaningful bonds as an adult. It is believed that unconscious patterns become set in place by the time we are approximately two years old. Our attachment style is at the core of how we form adult relationships, whether they are romantic or friendships. Furthermore, these "styles" often influence how we relate and respond to the external world and how we process things internally and relate to ourselves. The ultimate goal is to be able to develop a secure attachment style not only with others but with ourselves as well.
