female friend of boyfriend who comes off as really bitchy

[winneythepooh7]

OK I am starting to get REALLY annoyed. I hear at least 3 times a week especially how this chick "can't stand" one of my sisters (who did nothing to her except date one of her friends for a second). ANYWAYS maybe I am making a big deal out of nothing, but tonight me and my boyfriend are supposed to be hanging out. He called me earlier at work to say he is going over to her house for a little while to hang out. I've tried calling him back SEVERAL times to confirm plans for tonight and his phone is OFF. Oh, to make it more interesting, I also have heard a couple times this week how one of her really good friends can't stand my sister either. It makes me really wonder what is being said about me the way they bad mouth my friend they don't even know. I am starting to feel like when he is around her, everything, and everyone in his life needs to be approved and I am getting really pissed off.
