Have you read "Love Must Be Tough" by Dobson? It is REALLY good and mirrors DB strategies in many ways. It discusses letting go and detachment as the only way to regain respect from your spouse. Neediness, clinginess will cause him to close the cage door...he likely felt trapped in the M. It is the hardest thing in the world to do, but you must move on in his eyes--no matter what the outcome it is the best thing. I highly recommend this book.
Also, Homer's "Stop Your Divorce" is kinda strangely written, but offers some great advice to put things in perspective. Let me know if you would like to borrow a copy.
