Sorry but I got to disagree 100% with your p.s. note. Its already too hard to handle on his own that's how he got where he is. You leaving him now for having another drink seems patently unfair to you both. AA and/or counseling should be a part of his and your life ASAP. That's a solution. Expecting him to quit cold turkey on his own with you possibly leaving him also hanging over his head is a recipe for disaster. If he means this much too you, start making call now.
