Sm- good he is not in your apartment. He will be back, I think. I also think he is doing exactly to his family what he does to you and everybody. Finding any way to get another drink. He will stay out in the cold even if he has a place to stay so sympathy will kick in with someone and he can then use that money to drink. He will use up his family until he is asked to leave- then come back to you, so long as he can drink.
A harsh reality I learnt for myself- all by myself. I had to adult up and get sober and stop being a S..T to anyone I thought I care about (I still do). He needs to want to and show it by action- not just 'I love you, I am sick, I am cold, I promise, this time, don't you love me?' stuff. In that state for me- all that mattered was having enough alcohol to go to oblivion. I do empathise for him, but being an alcoholic and being in pain does not give any one the right to stuff up any one else's lives. Stay safe. Keep posting.
