I'm a recovering alcoholic. I personally do not have any alcohol in the house and I tend to avoid pubs because they revolve purely around the drinking of alcohol and I'd rather not torture myself frankly.
I have exceptions to these rules, eg if I have friends over for an evening that enjoy a glass of wine, I'm happy for them to bring a bottle with them, and if I am going to a pub for a specific reason ie a meal for a friends birthday, then I will go and enjoy myself, but probably not hang around for ages if the meal is going to progress onto a long session of evening drinking.
In other words, I'm not prepared to cut myself off from the world and sacrifice my social life, but I have boundaries around alcohol that are important to maintaining my sobriety and peace of mind.
However, the sole reason I have these boundaries and am able to maintain them is because I really want to. I have accepted that I am powerless over alcohol and that if I want to lead a happy and decent life then I must abstain completely. My sobriety is everything to me because without it, I'm fucked. There is no cure for alcoholism. You are either an actively drinking alcoholic or you are a sober one.
Your dh is in the grip of a horrible destructive illness that has nothing whatsoever to do with anything you do or say or try. He can only help himself. Nothing you do can make any difference. So with this in mind, do only what is best for you. Time to think only of yourself and your kids if you have any. If you want to leave then do it. Do not stay thinking that your faith and strength can help him. It won't.
Alcoholism will turn the most kind hearted, intelligent, empathic, wonderful person into a self centered, dishonest, self pitying, self loathing monster. And you don't have to live with that.
