The choices will come home to roost for the wife, and there will be more pain, fear, regret, guilt, etc. I seems that WAS's can't use any logic, as it is a pure EMOTIONAL decision. We all know that emotional decisions are usually bad. You have hit it exactly, on what your job is.
I tried the other nice guy method and it was worse(especially for me). I think C-Bart is correct you have to move out of your comfort zone, for YOU. Praying for you man. I know it hurts, I am there.
