Coming to critical engagment Book

I found this book in my library today. It brought back many feelings as I read my notes & all of the colored markings. I read this book about five years ago while trying to understand why my marriage was coming to an end. I had tried saving the union in the previous six years. Honestly, logic and reality seemed like insanity. At that time, I was going over my past delving deep into my conscious mind of events, behavior wanting to know the reasons why our marriage had failed. I wanted to see both of our responsibility in the ending of a 25-year marriage. I could not put this book down once I started reading it. This book is not a marriage counseling book. It goes into logical reasons why some marriages are a failure before the start; the dysfunctional behavior brought into a marriage that is a loaded shotgun and myths of expectations.
The advice on how to live through the ending of my marriage established some standards for me that soften my grief and allowed me to move on with dignity, understanding & kindness toward her & her new husband.
One profound thought in closing that I learned from this book which I believe is the truth; "We live out our adult relationships from the experiences of our childhood."
