Welcome to SR puckettcg, as has already been said, he has to not only want sobriety himself, but he has to stay sober him self, you can not make, love, or wish him sober, only he can do that.
What I would say is what some others have said, take care of your self, seek help & support on the Friends & Family forum and even better yet go to Alanon, meet people face to face who have dealt with or are dealing with just what you are going through right now. Trust me, there are far more vixtims of alcoholics then there are alcoholics, you all need recovery every bit as much as we do.
The best thing you can do for him is to take care of your self and not let him possibly take you down with him if he goes.
