Kimmie... I think Swimmer puts it well. In actual percentages, DBing may not work a ton... but it is a huge increase over the virtual nil turnaournd rate wheren no efforts are applied.
Furthermore, I applaud people like Michelle, Dr. Phil, Dr. Laura and others that try to shake up and shake off our divorce culture because it is killing us. I believe we as a society are in danger of imploding.
The DB percentage results may be only a small first step. Hopefully part of a turning tide. I know I want my kids to have a chance at a great and happy lifelong marriage.
