This book is only good if you are in a relationship with an emotional healthy person or...a person that is sincerely "trying". This is not a book that will help a person that is with an emotionally broken, manipulative or egocentric person. It is not all bad BUT if a person is unaware with who they are with or who they are, this book will completely empower and excuse disfunctional behavior. This book is not for everyone. And there are a lot of emotionally broken people that will be empowered by a person following this book. Its will give them the opportunity to take and take and behave poorly without consequence.
