so my girlfriend decided to be friends with her ex again after she had decided to originally block him because he was only a distraction to our relationship. when i asked her why she said they had an understanding and anything more than that was simply none of my business. we then broke up a couple weeks later and i found out she was sleeping with him again and she claims she didn’t cheat on me with him but i’m not too sure. i found out from him and he claims they were messing around a little bit before we broke up. anyways you things got bad between the two of us and we are no longer friends. i just want to know if i had a right to inquire and know what was going on between the two of them. i get its none of my business now that we are broken up but while we were together i feel i had a right to know. and for future reference.
