If you have any questions if you are with a abusive partner or you are abusive this books defines the abusive tactics. I found that I have spent so many years feeling guilty for not being able to accept the extreme highs and the bottoming out every couple of months and why I felt that I needed to apologize and take responsibility for my inability to be what he wanted me to be. This book is well written and in an approach for anyone to be capable of understanding what the patterns of behaviors the abuser consistently acts act. Your actions in response to the actions and the overall impact on the victim. Highly recommend this book it’s also not just for a spouse this book explains how it could be anyone in your life from work to family.
