"She hooked up with my ex after he dumped me and then she lied about it!"

I was best friends with this girl Claire. We met in 7th grade, and we were inseparable in middle school. When high school came around, we were just as close, but then we hit some rough spots. She started changing and became inconsiderate and ice cold to everyone. She bleached her hair and changed how she looked completely, and she thought it gave her the right to treat everyone else like scum, as if they should be kissing her feet. She did some horrible things to me, too, but I forgave her because we'd been friends so long. When we went off to college, we decided to be roommates. I liked this guy, and we even hooked up. We had been hanging out when one day he just went off on me, telling me I was annoying and he didn't like me and to get out of his dorm and never come back! She was right there and saw everything. She came back to the room with me and watched me cry about it, but said nothing. She didn't think she should be on my side, but as my best friend, I thought she should have been! Instead, she went back up to his room and hung out with him and his friends. To top things off, I just found out two days ago that she'd been hooking up with him whenever she told me that she was having a "girls night" at my other friend's dorm. When I confronted her, she denied everything. It took about three hours to get the truth out of her. Unbelievable!
