Visiting In Auburn..

So every weekend I go to Auburn to visit my boyfriend. His roommate has this god awful girlfriend that I cannot stand. Since day one she hasn't even acknowledged my existence. She would come in the room and say Hi to my boyfriend and not even so much as look in my direction. I was the first one to say anything out of the both of us, so at least I tried to make an effort to get to know her. She certainly wasn't aiming to get to know me. I am a shy person, so it is hard for me to talk to people, especially people I don't know. I talk to Dalton(my bf's roommate with the annoying girlfriend) and his other roommate(Brandon) is kind of a recluse and sticks to himself, so I don't really see him anyway. Ok, back to the story. So my boyfriend and I got back from seeing Due Date(which was a decent movie by the way), and I come in and go to my boyfriend's room to go the bathroom. Wes(my boyfriend, figured using names will be easier) goes into Dalton's room to talk to him and Toni(Dalton's gf), and Spencer(mutual friend). Well I usually don't ever go into Dalton's room and "socialize" but I figured I would last night just to try to break out of my shell. Wes knows I don't like Toni, and told me to chill out and try to be nice to her, so I figured I would since it is his friend's girl. I come out of the bathroom and make my way into Dalton's room. Dalton is in his bathroom, Toni is laying on his bed and Spencer is just chillin in the corner in a chair. Two seconds after I walk in, Wes turns around and says "Whoa! When did you get here? I was just talking about you." And I reply "Like 2 seconds ago" to which then Spencer laughs. Well I didn't want to ask my boyfriend in front of them what he was saying about me. I waited until we got back into his room to ask him. So here's how it went:
Me: "So what were you saying about me before I walked in?"
Wes: "Well I was talking to Toni about how I like Brandon's new girlfriend better than his old one because she actually talks to people and his other girlfriend didn't like to talk to anyone. And Toni was like 'Well your girlfriend doesn't talk to anyone.' Then I said that's because she's in the bathroom. And Toni said she feels like you don't like her and I said 'that's because she doesn't like you'"
At this point I am LIVID. ABSOLUTELY LIVID. I am sure that everyone heard me yelling at Wes saying words that wouldn't exactly be listed as friendly. But he had no right to tell her that I didn't like her. If I wanted her to know, I would have told her myself. Nothing can ever stay between my boyfriend and me which really pisses me the frick off. What's worse is I looked like an idiot just standing there in Dalton's room next to my butthole of a boyfriend having no idea what he said about me before I came in. And to top it all off, I was trying to be okay with Toni. I was going to put my differences aside and try to get along with her, and now every chance of that is currently ruined. But really and honestly I don't care to step it up and pull her aside and clear the plate. I just don't aim to please her or be her friend. Much less get to know her. I just don't want her to actually know I don't like her because she is the type of person to not let it go. So I come in tonight and she has the nerve to try and make cheap shot remarks directed towards me. I mean, since day one she hasn't even tried to get to know me. At least I tried. From now on when I visit though, I am not even going to acknowledge her. I don't have time to associate with trash. (She really is trashy, I would tell you why but it's not too appropriate. Let's just say it's not a pleasant noise to wake up to in the morning, or any of the 5-6 other times throughout the day that you hear it/her).
