My friends are assholes and dealbreakers with my girlfriend?

[Will]

So I've been dating this girl for about 9 months. I have a number of female friends and acquaintances at college. Now, since around the time we started dating, my girlfriend and them have not clicked. The first time I had one of my closer female friends meet her, it was at dinner and we met my friend there. In retrospect I was idiotically idealistic thinking they would hit it off, but my girlfriend, who's normally super friendly, barely talked to her. My gf said she tried to talk to her when I got up to get more food (we go to a university and the dining hall is buffet style), of course I only learned this months later.

A few months later, after our winter break, she starts saying all my female friends hate her. They give her dirty looks, say bad things to her, etc, she says. A few times the same female friend we had dinner with invited us over, which my gf said was an attempt to make her look bad. I asked my friends about them treating her badly, and they said other than not saying hi because they felt awkward and didn't really know her, they weren't being assholes to her. And this got them feeling uncomfortable around her, so now they did try to ignore her a little. My gf is convinced the original friend at dinner hates her, which she does now, because she made me send a drunken message to my that friend saying we couldn't be friends anymore because of how she treated my gf. I talked with my friend and apologized and she said understood the situation, she saw I was head over heels with my gf and forgave me. Somehow my gf heard about this and did not break up with me.

Anyway, we get into a lot of fights over my female friends, but then summer rolls around, and they're no longer a real concern. We still get into fights over it occasionally, but just some small spats, nothing serious. Fast forward to this current semester. I'm abroad, and so are a lot of my friends, including the female ones. One is still on campus, and my gf says she stills treats her like shit. It got to the point where today she demanded me to unfriend 3 of them on facebook, which I did, because I was so in shock at the request/am not ready to lose her, because I do love her a lot.

I know it sounds like she insanely jealous, but a lot of my females friends I'm not too close with. I only call them friends because I don't know what else to call them. I'm not really close with them, it's more like we're in an extended group of friends, so i could easily see them being a bit cold with her. I'm just not really sure what to do. I love her to death, but I hate the idea of burning bridges with anyone.

What should I do? I want to stay with her, but the way she and my female acquaintances are...well, I can say having strained relationships with them has already strained some of my actual friendships.
