Every situation is obviously different, but the last time I caught AH drinking before I asked him for a divorce and asked him to leave, he told me he was drinking because he felt suicidal. In my experience, AH felt like drama=drinking and the more dramatic his excuse was, the more excusable his "relapses" were. I think you did the right thing talking to a mental health professional, there is not a lot you can do other than that.
