Hello I am so blind,
I’m sorry his alcoholism has brought you to this point of worry and concern and fear. You can’t save him. If you are like the bulk of us here, a small part of your mind think you alone can save him. So you are torn.
I don’t know how much work you have done on yourself and how you got mixed up with an A, but there are a lot of threads on this site with great book and article recommendations. You don’t want to pick another A, so please work on you and see what drove you to fall for one...
Take care of you.
