After that I told her I wouldn't take this anymore, and I didn't want to see her thereafter. She said that she never was interested in sleeping with me anyway (we had been doing this for two years at this point), and denied all responsibility for anything. She said I had no right to take advantage of her and she did nothing wrong, even though she made a habit of insulting me in public and kicking or hitting me when she got upset. The fight split up our entire group, with some people siding with me and some with her, more based on personal feelings towards either person than knowing the details of the fight itself.
Its been close to a year since this happened now, and I've recently come back from studying in Europe. Needless to say there were thousands of miles between us, but now she starts messaging me again asking when I'm coming back and that she wants to see me. I've ignored the messages thus far since I know responding will only cause me problems, though its hard because half my friends at school are still involved with her (same social circle, some live with her). What should I do in this situation?
