If your goal is to save your marriage, do other things first...
SG, he has -- go back and read his old thread. He got horrible advice back then, in my opinion, I told him it wouldn't work, and it hasn't.
I'm not always in favor of a tough stand, but if the past marital style for him is to be overly pleasing and placating, I do think this can be very effective. He just hasn't tried it.
Isn't DB about trying what works, and throwing out what doesn't??
