I agree with Tuffgirl - you didn't really do anything wrong, but he probably interpreted it as a play for attention. Just leave him alone for now on. Why waste your time.
I am sorry you are hurting. It really stinks to stick with an alcoholic through thick and thin and then to be set free just when they seem to be getting better.
But I truly believe that IF it is meant to be, and it may not be, that it will work out in the end.
