...sigh, heres a real answer.
People that think they are badasses/cool/popular have one and only one weakness. they can't torment someone that is a strong person(not literally strong, mentally strong). If they say something, just smile. If they say your not wanted by anyone, well, thats a typical girl thing to say, its not true and you (should) know it. what you should do is try to appear stronger mentally. Get a good group of friends that you hang out with alot, to where if the prepbitchsquad talks shit on you, your friends will be there to back you up.

i know the position (sp?) they're in because my ex-bestfriend went out with someone who made my life a living hell
(he always made fun of me and told me to kill myself) and i knew her for 5 years and she kinda picked him over her (then he broke up with her...) but i never made her pick because that's her life not mine

tell them how you feel you should tell someone after you talk to them and they still doing those things... if you don't tell or try to talk it out probably wouldn't end for sometime

but it might be hard being friends with them you probably hurt their feelings and lost their truse, same with you... but you can try if you want
but no offense it was stupid for you to pick a guy over friends.. (if they were really your friends) and it was stupid for them to make you choose
but they should forgive you cause it's in the past and if they keep hanging on the past it's really immature....

oh and ignore the people talking about your spelling lol
cause i know my post have near 100 spelling mistakes
