Oh I see.
Still, putting him in his place (though it would feel SSOOOOOO good) wouldn't accomplish much. It seems like you've come to the place "knowing your own truth" and not needing him to validate that anymore, which is awesome.
I don't know the particulars about your situation or how you plan to leave, but in my case, I had to "play nice", even taking my infant daughter to him for visitation twice a week, knowing full well he waited till I left to drink, until I got full custody and my divorce. After it was all over, I was glad I held my tongue!
