<human>: Can you give me the gist of the text in a nutshell?

My brother drinks/partys a lot, and sometimes when he gets really messed up he has really bad fits of anger. Almost every time he gets drunk he becomes somewhat narcissistic, obnoxious, and pretty rude. Now I like to party as well, but not nearly as much as he does, nor do I ever get angry/mean. In all honesty I don't really care for my brother's personality at all when he's drunk, and unfortunately I think it's creeping into his sober personality more and more.

He's had an apartment with one of our good friends, and it didn't go so well. He trashed it a few times, had people over to drink like every other day, etc. If I remember correctly they got evicted because of all the problems. 

I want nothing to do with that stuff. I'm pretty introverted, so I wouldn't want people over everyday. Close friends are cool but I definitely need some "me" time to recharge. And due to health issues/personal lifestyle, I would not be partying that much.

**Would it even be worth it for me to voice my concerns with him before I move into an apartment with him?** I'd most likely let him know that if he pulls the stuff that he has before that I wouldn't stay. 

He's a good dude at heart. We're into a bunch of the same things, have tons of friends together, have great times, etc. I know he's capable of being a good roommate because we share a lot of the good traits, and I'd love to get an apartment with my own brother but I don't want to take a big plunge into something I'm not certain of. 

*****

With all that being said, I have another good friend who wants to get an apartment with me. He's an overall great dude, and he's one of the very few people I actually look up to. However, I would feel bad about leaving my brother behind.
<bot>: Have a brother who likes to party, gets really angry when drunk, has a lot of friends over. I'm introverted and don't party constantly. Can't decide if it's hopeless getting an apartment with him.
