answer:I’m sorry that you are dealing with this. I’ve got friends and relatives who are alcoholics and two of my grandparents died from alcoholism. However, in my opinion it’s not your business or concern to worry about him, or wonder what will become of him if you bail on this shitty situation for your own good. Even if he were your friend or your brother, it’s still not your responsibility what happens to him. He’s making the decision to fuck up his life, and as long as you feel like he is your responsibility, you are allowing him to fuck up your life as well! If he has the self-awareness to warn you back in October that he is an alcoholic, he already has the choice to clean himself up if he wants to. Some people really need to hit rock bottom before they seek help. And you can’t do anything for him or induce him to give a shit. Alcoholics delude themselves first and then try all sorts of crap to delude others (including saying they’re getting their act together, or being “good friends” when they are sober so you feel solicitous and hopeful towards them, etc.) On a practical level, my only suggestion is to save up your money and look for another roommate, or a single apartment with cheaper rent somewhere. I’ve had a lot of friends have success with advertising for roommates on Craigslist, although I have not done that myself. Best of luck to you.
