I've been with this girl for a year and a half on and off. Im deeply in love with this girl and we broke up about a month ago and she has been talking to her x before me again and it really pisses me off. Should I say something to him or her. She also still tells me she loves me and she misses me but doesn't want to be with me. But I would do anything to get back with her. So what do I do?

Well it seems she's expressed the way she wants things to be. She "doesn't want to be with you." It isn't your place to meddle in her "affairs", so to speak. Especially since she'd said that. If she still loves you she'll come back on her own. It isn't time to push her or comment on her male friends. That usually pushes a girl away. I would wait things out and see what happens. See what she does. If you really love her than you'll wait.
