I am in the same situation but I am just getting to the point of taking care of myself first and not worrying so much about him.
He went to AA on his own but then he was clean for about six months then he came home with a six-pack and said he just wanted to drink one..which he did...the only thing I think of now is oh great this is the beginning all over again. I am just numb as to what to do or say to him anymore....I dont want to fight about and I dont want to hear his I am going to change scenarios again...and he doesnt want to hurt me...his actions are so much louder than his words.....Oh well this is the life?
