When you say, "bought the book" do you mean "Divorce Busting", "The Divorce Remedy" or "The Sex Starved Marriage"? Think one really has to have read one of the first two to get the most out of the third.
I'm just wondering...
Another really valuable book is "The Five Love Languages" by Gary Chapman. Have you read that?
I think many of us are familiar with the marriage builders site. It seems like a good one when two people are willing to work at things. Not sure how well it would work otherwise.
Glad things are working out well for you! Congratulations!
