My AH stopped drinking last year in July. What I didn't realize at the time he stopped, was that it wasn't the ACTION of drinking that was the problem in our marriage, it was the ATTITUDE of alcoholism (verbal abuse, emotional abuse, manipulation, coersion, etc) that was destroying me and my relationship with him. He stopped the action, but refused to even acknowledge the attitude he still lived in every day.
I, like Barbara, AM living a "happy ending", a more fulfilling, happy life - but it is without my (now sober) alcoholic husband.
I hope that no matter what HE does, you make the choices YOU need to make to take care of YOU. (((hugs)))
