Hi Sarah....welcome to sober recovery....happy you have found us.
First off you need to take care of YOU Sarah. Your b/f is in charge of his life, and there's not a thing you can do or say that will make him stop drinking, that's totally up to him I'm afraid to say, so until then, you take care of YOU.
Lots have given you great advice. I think meetings for you would be wonderful, you'll get the best support there, people who totally understand how you're feeling with this, they've been there, or are still there.
Wishing you the best on your choice, in finding some happiness.
Love and hugs.......Denise
