My girlfriend cheated on me with her Ex did I make the right decision?

he shouldnt have anything to say to u. he shouldnt have done that and neither should she have. most girls and guys... once cheaters will most likely cheat again.. i would keep it as u guys stay friends. u let her have that freedom and she did that anyway. u will never have the same trust for her and that will always be a problem in your relationship, expecially if she does plan on still bing friends with him. she had no reason to do it and there is no reason to get back together. and i wouldnt wanna c him. he knew about u and her and he shouldve accepted that and known that that wouldnt be ok.
