And I don't know what to do about it. He started drinking excessively about 1.5 years ago now when he'd left out of state for school. Upon finishing school, he returned home and began drinking very heavily. Just about every night, with rare exception, he'd drink to the point of passing out. With this came all the typical alcoholic symptoms (mood swings, spending less time with family, etc.). It continued to escalate and while it bothered me, it really didn't get bad until one evening when he crossed the line. I'm a performance major in college, and had a particularly important show that night with a new band (my first own project), at a new club. Since he's family, despite my apprehension I felt obligated to invite him. Sure enough, he showed up and got absolutely trashed. He actually fell out of his chair at one point, and just generally made an ass out of himself. What really got to me, though, was that this show as huge for me. He knew that, and he couldn't even show me the consideration of showing up sober and listening to me play for an hour before getting wasted. I'm sure he doesn't even remember being there. This was months ago now, and I still haven't gotten over it. He hasn't even tried to apologize or make amends for it, and I feel I can't bring myself to forgive him for it until he does. Anyways, a few weeks ago, he started to clean up his act and has since been sober (as far as I can tell) and has been behaving appropriately. This puts me in a tricky situation, because at this point I don't care to tell him about any future shows I have purely out of anger, regardless of whether or not he acted decently at them. At the same time, I feel like this is an immature position to take because he was an alcoholic then, and somewhat out of control of his actions, and he IS family. I just really don't want to compromise my own feelings to give his alcoholism a free pass. What should I do?
