Literally gave me the hope to fight for my marriage & fight for self healing, this book is very insightful about real life struggles that end up hurting us & our marriages, it all starts with you, if you work on you & your issues, you will begin to find personal healing which in turn, leads to healing within the marriage, if you DONT work on YOU FIRST or THINK ITS ALL YOUR SPOUSES/PARTNERS FAULT, your marriage will stay the same or get worse & fail. It's a great read to read by yourself, or as a couple or even in a small group. I highly recommend this book.

Powerful information for any couple

Format: Kindle

My husband and I are in a good place now, but spent close to 18 years in toxic patterns. We separated 7 years ago for a brief period and have been reconciled and building on a more solid foundation. I wish we would have had this book then! This book has great tools, no matter what season of marriage you are in.

Worth the Read

Format: Kindle

This book covers examples and advice for several different specific scenarios and struggles in marriages. Not every chapter is directly applicable to your situation, but I believe all of the advice was useful, even if indirectly. I feel encouraged, better prepared, and less fearful after reading this.
