I wouldn't worry about the "degree" of alcoholism he is inflicted by. That is when we make things more complicated. Dont worry about whether or not it will get worse either.
Focus on you and how much it affects you. Look at that post, you are hurting and it isn't fair. Now is the time to find something to do about it. Are you working the steps? Who wants to live with that kind of irritation everyday? You must be worried sick with all of that drinking.
Take care of you and find a way of dealing with it, in such a way that it makes you feel freer and happier. (((hug)))
