For the past couple of days, my ex-girlfriend has been ignoring me. She doesn't want to talk to me during school at all. She just instant messages me and asks me for help for homework.. [Sigh] I say hi or ask her questions, but she won't answer at all when I get a chance to see her. We left off on good terms when we broke up, but why does our friendship have to go to waste like this? Should I confront or just back away?
