I read the book that goes with this, Relationship Rescue, as I worked through the workbook. If you don't have both, I highly recommend you get a copy of the one you're missing, as the program is really enhanced if you have both and read the book as you go through the workbook.
There are some tough questions in here that ask for your total honesty. Some answers you give may hurt your heart, but that is okay if you are truly trying to help your relationship or just yourself. A lot of these questions are in the beginning. Keep going, it does get easier.
My husband, Sean, and I, had a ton of fun with this. I am on a relationship book kick right now and I don't read these to seek help for our marriage. They fascinate me and we always do the exercises and end up really enjoying them. While I'm not trying to fix anything or save anything, we've still learned a lot about each other and have had a lot of really deep chats.
This is a really great relationship program and if you do it honestly and follow through, I believe it could be of help to a lot of people. Please remember, you are writing in this, and that makes others curious. If you want to keep this just to yourself, find a safe place to store it. A lot of questions could provoke answers that may upset some partners and there are people out there in dangerous situations. Find a safe place for the book and yourself if you are one of those people.
