Help me! friend problem.pleasee!!?

okay so i moved to Tennessee in the middle of the school year of 2009-2010. My new school i was only there for the second half of that year. I was quiet but i did have my friends abut we weren't close. This year we got closer but now one of y friends thinks i stole her friend from her. shes telling me i should leave the school and that all i do is cause her and this girl to get in fights. Shes cussing us out right now and keeps calling me a *****. its really upsetting us and i don't know what i should do. I dont know if i even want to be her friend any more im tired of it.
