Thank you everyone. I feel a little better, although I'd like to punch him in the face, honestly. So I'm still pissed off and resentful.
Wisconsin, You are probably right that my daughter notices things. But she seems happy and unaffected for now.
I don't believe in making threats, and I can't leave at present anyway, but in the past I told him that if things continued the way they were, I would be leaving at some point. He begged me not to, and I told him it's not a threat, it's just a natural consequence of his drinking. As I said, I cannot leave right now, but I will NOT raise my child in an alcoholic home.
