In retrospect, I think you're right. I don't know that you've read "Love Must Be Tough" by Dobson, in it he absolutely stresses that that is the only way to get a marriage back on track and the sooner the better. Unfortunately by the time I read it I had been separated for over 6 months and pretty much had left the door open inspite of all of the crap husband handed to me and all of his bad actions. Dobson's thinking is that when you go along, cry and beg, the WAW loses whatever respect they have for us. Especially if they are reliving or trying to recapture what they think they missed out on. They look at us like we are an obstacle in their way and they resent us for it.
Makes sense to me especially now that I can see it for what it was.
