We argued last night and he said he resents me because I don't let him drink.
That is not entirely accurate because he is, indeed, drinking. He might be resentful that he feels like he should not, or that you don't support his decision to drink. The thing is that is his issue to work out now isn't it? What are you supposed to do about his resentment? Ohhh - maybe he is implying that you should be more supportive of his decision to drink or binge. Kind of crazy when you think of it that way isn't it?!
I just can't be a part of the drinking.
That is good to know about yourself. That is like a boundary. It is a good one too. One that is in your best interests. How do you protect and uphold this boundary?
It seems like he wants to drink, and you do not want drinking in your life. A bit of a crossroads.
Al-anon meetings were helpful to me. I also liked the book 'Co dependent No More' and the stickies also helped me out a lot.
