I think you should talk to your husband frankly and explain your feelings. He may dismiss you but you have to make him see this is hurting you.
Do you think I will ever get to the point that I just don’t love him any more and can let go? There is a part of me that says (I HOPE SO) and a part that hates that idea and just keeps praying he will stop. but I know that won’t ever happen. (Heavy sigh)
From this statement I think you still have feelings for him and you just feel burdened and in a way would like to be released from it. In your conversation include that you feel like you are falling out of love if that's how you feel. He must know the gravity of his drinking. Let him know that you'll support him in recovery. Remember that he probably thinks his behavior is reasonable and he must see you are serious. As an alcoholic I justified my drinking as normal when it certainly wasn't; alcoholics make good liars, especially to themselves.
