What do i need to do, we been friends too long to end over a boy, im the one that should be mad!?

ok so i had 2 bestfriends we are all 15 and we have been like that sence we were in the 6th grade now we are in the 10th and we does everything together. but anyways i liked this dude and i was like hey hes cute so we started talking for liike 3 days cuz i had to go to another school for like 2 weeks from some family issues. when i came back one of my bestfriends was datin the dude. i did not get mad or anything because it was just a dude but i coludent believe that she would do that to me. they was together for two weeks. so me and him started talking again we never went out and she going to get mad talking about im fake and all this stuff so i was like what ever i dident have no time for this i got a life to live. me and the other 2 girls share lockers we havent talked sence 12.18.10. and its kind of weird walking to the locker everyday and all three of us are there and we never say anything to eachother i let it go but people say that me and her act so much alike thats its funny. but my other bestfriend says all she wants me to do is kiss her *** but im not doing that and i dont think i should say sorrie to her. the dude texed her and was like y are u doing this u have no reasion to be mad, it was only two weeks and stuff like that.... nowfriend she lives right next door to me and i knew her for 5 years and we have became very close and we put up a lot of pics on facebook so my ex-bestfriend texed me and was like soo i see you have a new bestfriend i told her to stfu and to kiss my ***. i should be the one mad not her. and everyone says me and her need to be back friends cuz its weard seening us not talk. i have no contact with the dude now what so ever we dont even say hi in the hallways anymore. so ive tryed talking to her but she acts like she has a stank attitude so im not going to kiss her *** i came in 2011 without her i can finish without her...and yes i do pray to god to put us back together and i know it wont be the same but its over a stupid boy! grow up!
