Broken up, Should I move on with my life or try to work through this?

This was my first serious relationship, Me and my friend went from a normal relationship to a long distance relationship…..been together for 3 years with the third year (which we just made in august) being long distance, When we are together, in person we rarely ever have major problems and we are happy, but 99 % of our problems arise through long distance. My girlfriend cheated on me toward the end of the third year (long distance) and was eventually honest about it and told me. I decided to forgive her and try to work through this problem because I loved her too much and would have been happier with her than without her, I always said that everyone deserves a second chance, the natural problem was that I would always bring it up and could not stop questioning her for the next month, the trust was not there and it was all really messed up. She ended up breaking up with me a month later, her reasons were that she felt like she owed me, I lied to myself and I needed time to try and move past what she did, and we basically both needed our space to try to come to a comfortable level in our personal lives. Long distance has just proved to be too hard for us. She told me that she wants to try again in the future when I graduate from college in May where could be in a face to face relationship again and that we use this time to build our friendship and concentrate on being happy. I told her that was all well and all but that it was unlikely because she was going to get with other guys and how is that going to help us?...... that was one of the major factors in our downfall to begin with. Then she went on to tell me that she will not mess with other guys throughout this break.....that she is not even interested and if for some reason she was to do something, she would tell me in a timely fashion, she said if she was to do anything she would explore with other girls!!!!....I told her I guess I could handle that if we get back together because I don’t see them as a threat once we try and move on….. Basically this break is something that was needed and will help us out in the future if we plan to make it in the long haul….what makes it complicated is that we are not telling our families because our futures are up in the air, we have 2 flights booked to see each other during our break, one is in less than 2 weeks the other in 2 months and we are going forward with them. Me and her also said that we would still remain intimate in bed during this break (friends with benefits). And we still talk on the phone on a normal basis. Should I just cut all of this off and move on with my life, or should I try to move forward with this and see if we end up making it work? I know if I move forward with this plan It could turn out to be one of the greatest decisions I ever made or the biggest heartbreak and waste of time.. So far Im leaning towards going on with the plan cause Im stuck on this girl, it's all I ever knew for the last 3 years and 1/2 of my life, we live together!....Help!!

move on, life is too short to deal with these sorts of things. if he comes back, let him, otherwise, just let go.
Reply:Move On. If she was unfaithful once chances are she will be again. Once a cheater always a cheater. That is true 99% of the time. Believe me I've been there and done that one.
