Two days ago, I came back home from a trip to find out from my boyfriend that he had cheated on me with his ex. It's not only the cheating, but also the fact that it was with this particular girl. Throughout our relationship, he still had feelings for her. He lied to me, and continued to tell me that everything was fine and that he was over her. I tried to break up with him before because he continued to talk on the phone with her, but then, we continued to stay together on the premise that I would trust him and that this ex would not be an issue anymore. But, obviously, this did not prove to be the case.
I've cried so much and these past couple of days have been quite difficult. He is trying to apologize, but that is not enough. Despite all the wrongs I've suffered, the thing is, I would like to be with him again at some point... because we had our moments of happiness. Definitely not right now (although it is tempting), but perhaps when he is truly over his ex, and when he can build back the trust between us again. Do you think this is a reasonable possibility????
So, basically, my question is: How do I find out how he truly feels about his ex? Should we take some time apart, or do I move on? How can I ask him to rebuild trust without us being completely together at this time? How do I ask him to take time apart from me and see what the furture will hold? Can we and should we be friends at this time? This is especially important because we work together and he lives in the same apt building as me. Or is it more important that I just "burn the bridge"?
