Hi,
Sorry to hear this, its a miserable situation. I actually wrote a reply to you, then deleted it as I felt I wasn’t qualified to give the advice, when im in a relationship with an alcoholic! Im good at giving advice, but dont take it myself.
I think the cold hard truth here is, he will not change if he doesn’t want to. You can’t do it for him. You have to decide if you can carry on like this? Have a talk with him, let him know how bad things have got for you.
