Yes, he drank when I first met him and smoked pot. We were both young so I didn't think much of it. After we married, I realized it was a problem for him. I stopped drinking much after our first child was born, but he was drinking more and still to this day drinks more and more. Funny our oldest just asked me recently if his Dad was always an alcoholic. I told him, yes, he was but I just didn't know it at the time. He said he didn't remember him acting drunk so I guess he managed to block out a lot of bad memories.
I think if I ever get myself out of this marriage to my AH, I'd be happy if the next guy said he didn't want to drink at all.
