Jo may be right, but I'm still going to play devil's advocate.
Is it fair to use the same principles for WAWs/ex-wives as for WA husbands/ex-H? Don't men and women respond differently. I think we do. Is it fair to apply the same principles in all of our situations? DB/DR doesn't say use the same techniques. It gives suggestions that can be used. It says do something different. One persons cheeseless tunnel may be another person's dairy farm.
But regardless, Gabe you know your ex-wife better than anyone. You probably have a sense how things will go over. All that matters is results.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
