<human>: Condense the text into a few key points

My roommate is an inconsiderate jerk. He has that rich kid attitude where he expects everyone to bend over backwards for him. He has blown me off twice on plans that we made to the point I don't ask or even want to do anything with him. For the past few days he has had this chick over 5+ hours. The first night she was over he was twitch streaming and when she came in he closed his game but left the stream open then went back and watched the whole thing over again. Yesterday they finally left the room so I figured I'd watch some tv. About 10 minutes into the episode they comeback in and on an Ipad start watching some other show turning it up so loud I couldn't even hear what I was watching. He never watches anything with headphones so today when I come in the room when I find him on his laptop I was thrilled that I could use the peace and quite to take a nap since Im feeling a little under the weather today. Around 30 minutes later he takes out his headphones and I'm awoken by music blaring. I don't know how to bring any of this up. I can't it anymore, all I want to do is yell at him but I've had to leave to room so I don't just snap. I'm not the greatest in social situations and I feel lost, I don't want to be a major asshole but at the same time I don't want to seem like someone he can walk over. I just feel lost. Any help is welcome and thank you for your help in advance.
<bot>: Roommate is a total inconsiderate rich kid jerk who doesn't seem to care about anything but himself and I don't know how to deal with it or even bring it up.
