Sorry for the reason that you are here, but glad that you found us! Please keep reading and posting.
So, whether he is an A or not doesn't really matter. What does matter is his drinking is having an effect on you...and it's not a positive one. Please educate yourself on alcoholism, read here on SR (the stickies have lots of good info), and I would recommend Al-Anon. You'll want to learn about detachment and boundaries...you can search for them on the forum. They are tools that will help bring you peace regardless of your AH's drinking.
One of the first things I learned here was the three c's - you did not Cause it, you cannot Cure it, you cannot Control it. They have really helped me a lot. One of the boundaries I set with RAH, was not to engage in conversation with him when he'd had four drinks in a day - it only led to me being upset or an argument so it was not worth it.
Hope this helps...this is a great community for understanding and support.
