Total mess looming - advice!

Hiya to all reading this,

So basically I moved into a shared flat for my second year of uni; me, my girlfriend and another person. I regretted moving in with her almost immediately and to cut a long story short, it isn't going to last. I think I love her, but if it makes sense, I don't like her. I don't get the impression that she tries to be a nice person and her views of the world make me want to just run away from humans. She brings out the worst in me, and I hate how she has changed me. I used to be a nice and thoughtful person, but now I don't even know what I am. Everyone says that I'm a good boyfriend to her. I guess I am. I adore caring for her, but I get nothing back. I'm sorry for the drama, but it's really destroying me. It's got to the point where I look around at all the nice people and wonder how I ended up with somebody so heartless and insensitive to other humans' feelings.

But I'm obviously stuck living here. So what do I do? Shall I try to keep it going? I'm scared of ending it because I know I'd miss her, and seeing her every day would be unbearable. And plus I know she'd be the sort of person to try to make things worse while I'm living in the same flat.

I don't even know if this is actually a question or just a rant to the internet. That's the beauty of the anonymous button I suppose. She's more or less my best friend as well as my girlfriend too, so I'm going to lose that too.
