So I've been talking to this girl for about a year now and we haven't really solidified things yet due to our long distance relationship. However we do act like a couple when we are together. The thing is that we got into a really bad argument and decided to take a break from each other briefly. When I visited her again, she had told me that she was seeing another guy and had also slept with him on a couple occasions. We got together again and tried to work things out when I was back in town and it was good. And then I left town again... We once decided again that we weren't talking anymore.. 3 months later down the road I call her up and she is ecstatic to talk to me. She really wants to get with me and re lite our flame, but the thing is during our 3 months off, she went back to the guy. She finally realized that she didnt really like the guy as much as she had hoped.. So here I am, wondering if it is the right decision to continue my relationship with her? We have never dated but I feel like she did me wrong.. I need some help here.. Thanks.
