Best Friends and Backstabbers

I'm definitely having the worst week I've had in a while. I love when people who you think are your friends, really aren't. I'm pretty green when it comes to the whole mating game. I'm not the type of girl to just dive in and go for gold. I typically enjoy getting to know people before I sleep with them. I met this guy last week and I came to the quick conclusion that I'd love to know him. I also made a point of informing my roomies/friends so that I wouldn't get screwed over. Apparently, that doen't work. Now one of my friends is going for him, wben though she's got a boytoy. She's the type of girl who could have any guy she wants; skinny and gorgeous. Of course the guy I was interested in, is now falling "in like" with her. Screwed over. Again. I'm so done with this crap.
