I have lots of little problems?

I'm really sorry! well in the middle of reading it i was going to tell you just stop talking to her and maybe that would help a little. but if she is friends with your friends it might be a little hard. you may not be the most outgoing person, but maybe if one of your friends isn't hanging out with her one night go out with them and try to find someone that you want to be with also. When my boyfriend of a year and a half broke up (he was my first real bf too) i met someone a couple weeks later. the relationship was a little rocky at first because i was obviously not over the person i had been with for so long, and we did break up for a while, and i'm not saying it will happen for you, but me and the "rebound guy" got back together and now are happily married and having a baby. all i can say is pretend it doesn't bother you when around her. try to find someone that can keep your mind off her like maybe a new gf...i wish i could help more, and i wish there was a perfect answer...but people deal with this kinda thing differently. but thats my advise to you...good luck...
