Roommate From Hell?

Baigen
I have a horrible roommate. I have no idea what to do. I can't even begin with all the things she does that makes me mad. 
Mind you I live in a suite, not really a room. We only share a common area. 
So my roommate has loud sex, comes to the suite drunk, talks about me, leaves the place a mess, then proceeds to leave me with her mess. 
It's awful. There's so much more. But that's scratching the surface.
