I just want to add something real quick. I cheated on my boyfriend about a month ago. He is deeply hurt and angry and upset and I'm sure I'm not even beginning to describe the emotions that he's been through over the last few weeks adequately. But, we were officially, honestly, no-doubt-about-it together, unlike you and your boyfriend. Even so, he has been communicating with me in a constructive manner. He does not bring it up in front of other people just to hurt me. He does not say things intentionally to hurt me (I get hurt anyway, but I don't believe he does it on purpose). He has even accepted that I am in a lot of pain as well. I think all of these things, as well as the efforts I've been making, point to the possibility that we'll get back together and work through it (that is by no means a certainty). I do not believe that is the case in your relationship. Yes, your boyfriend is hurt, but he is being vindictive and purposefully trying to hurt you. That is not a good sign.
