Make a decision as to what YOU will/won't put up with...and that's not an easy thing to do. It's up to the addict to do something sbout their addiction...YOU cannot do it for them. He must take the necessary steps when he's willing to recognize HIS problem. As long as he's in any way blame-shifting for why he drinks...he's not at the point where he will come close to taking real accountability...and taking the steps to overcome the addiction.
With my XH it took me finally walking out the door for him to get to that place.
