<human>: Can you provide a brief rundown of the text in within 3 sentences?

She broke up with me a few months ago, since then I cut her off completely. No contact. But the reason she dumped me was misunderstood. She didn't put herself in my shoes during an engagement conversation gone terribly wrong. I never got to the chance for her to hear me out. But I'm afraid that if I never contact her she will never contact me. I don't want to be told to just move because everybody tells me that. We dated for 4 years and we loved each other like crazy. Since then she has moved on (the same day as she dumped me), but I'm not sure if its a rebound or not. But anyway I never got a chance to tell her why that conversation went wrong and it kills me, because if she would have known before hand this most likely wouldn't have happened.
<bot>: want to contact her because I'm afraid this could really be it for us and im afraid It will prolong the healing process. Any advice on what I should do?
