Alcoholics are alcoholics, and they can't just drink less because that doesn't change the fact that they ARE alcoholics. They also hang out with and have friends that have the same problem. So, that means they have to realize they have a problem, stop drinking and go to AA meetings, often they also need to seek therapy and they have to distance from even give up their "drinking buddies" who will always encourage them to drink which is never going to work when one "is" an alcoholic.

Your behavior has gotten to a point where you are on this toxic loop of having to watch him and "hope" he doesn't get so drunk that he is a danger to others and himself. THAT IS NO WAY TO LIVE, and the healthiest thing for you to do is end this relationship and get away from this group of individuals entirely and seek out individuals who live a healthier lifestyle instead of seeking a constant escape from life through using alcohol.
