I dated a girl that cheated on me 3 times we broke up finally and I tried moving on. This didn't work so I said I'll be single, then I saw a guy trying to get her so I won her back. We dated but she couldn't leave the guy alone. She talked of change and never did, so to sum it up we broke up again, but I can't move on. I've tried to talk to others but I just stop before I get the nerve, and she won't leave me alone. She claims she is sad when we are together because she alway stresses me out but won't change so that I can trust her again. Then we break up and she feels like she took me forgranted because I took care of her. I don't know what to do my mind tells me to move on but my heart won't let me.
