for me, i would have dumped him at 2 months. blind drunk or not, i can't forgive that sort of behaviour.

BUT - you have been with him for a year after that event. he has only been inappropriate when he has been drunk. you have said he has sinced stopped drinking. i think i would stay with him and forgive him for his past behaviour.

if he does turn to drinking again, though, i would be out of there.
