" I also showed him the Al-Anon packet I received at the first meeting I just went to. "
RRY, I know that right now it might not make much sense to you but the same way you will learn at some point that his drinking is none of your business (I know it sounds crazy to you right now), remember that your going to Al Anon is none of his.
It should be an act of self care that you do for yourself alone the same way you might take a bubble bath or get your nails done. As you work the program, he may get better, he may get worst or he might stay the same. How he reacts and what he does is irrelevant, it's your time now and something you are doing for yourself.
