I think he did it to help him resolve his own bad feelings, and see if it could be done without hurting me. Needless to say, my reaction made him change his mind but I was resentful that he placed me in that position.
My boundary was that if I'm around and he drinks, I will remove myself from the situation. And I failed my first test miserably. I'm trying to be gentle with myself and forgive because it's the first time, but it was compounded by all his other comments that led me to believe he's not fully committed to recovery, but once again trying to 'do the right thing' because of how much it's hurt our relationship (and not because he's truly seen the light)
