Dear hopeless, welcome to the SR family, we are glad to have you here, please get yourself to al-anon and read the stickies at the top of the page as well as the stories from thousands who have walked this same road you are on now.
In my opinion it is unlikely to get better before it gets much worse, unles he acknowledges he has a problem and commits 110% to solving that problem, you are in for a long hard slog if you decide to stick this out.
You did not cause his drinking problem and nothing you do can fix it!
Please know this is a wonderful place with people who want to be there for you and want to listen, you need a shoulder or a hug, I will be there for you.
Best of luck to you,
Bill
