All the more reason to end it now, before it becomes even more painful. From my experiences, that's when they're the worst... Most of my classes are with 17-18 year olds, but I have a group of 15-16 year olds in one of my courses. Damn, some of the stories I accidentally overhear are ridiculously evil. This is serious emotional bullying they're doing, and it kind of pisses me off, but also makes me glad a heartbreak over the summer after freshman year, pretty much causing me to be an outcast my entire sophomore year. It's strange; nearly everyone I talk to seems to agree that sophomore year, or ages 15-16, is where people tend to be the most perverted/malicious... must be when hormones tend to peak for teenagers, or whatever. Anyways, I also went through a similar situation and I'd also like to say you should end it now, for a long time. She's taking advantage of your kindness and she knows it. I had the same thing happen to me when I was about your age, I ended up getting into a rather immature fight over it and lost two of my best friends, haven't talked to either in nearly two years, and am very happy I still don't talk to them. It was difficult at first, yeah, but time is really the only way to heal these types of wounds. A wise man once said you are the average of your five closest friends and yourself. Ask yourself, would you like 1/6th of your personality to be influenced by her? Judging by the information you gave us about her in your posts, you definitely do NOT want that. I'd recommend you find a few people you look up to in your classes (funny people, smart people, talented people, etc.) and ask them something like, "Hey, I've been having some girl trouble lately that's really been bringing me down, and I could really use a new friend. Would you mind helping me out?" Any guy worth being a friend would say yes in a heartbeat.
