My girlfriend broke up with me bc she told me she still loved her ex, who cheated on her after 6 months, so obviously I’m hurt and I’ve done nothing wrong, then she’s telling lies to her ex saying stuff and not being honest saying that me and her have done nothing together sexually and stuff, and her ex asked me and I told her the truth so the girl I was with started calling me a cunt and stuff to people to make it look like I’m a horrible person when she’s the one who played me for 7 months. What do I do?
