I had always had healthy relationships until that ONE GUY came along and took something from me ... an innocence, a happiness of sorts. It was after I broke up with him that I realized we were both codependent. His problems were somehow always my problems and my happiness depending on what mood he was in. This book really opened my eyes into what that meant and how I could change my way of thinking. I have carefully reintroduced myself into the world of dating, being careful to remember what this book said so I didn't fall into that unhealthy pattern again. I enjoyed the tests you can give yourself (I still sometimes do them) and the exercises in order to gain freedom from this mental state. I recommend it to everyone.
