My Ex Reached out

Hi All. So my ex recently reached out to me after 7 months of no contact. I will keep it short and simple and say how he broke my heart, (we broke up mid April), and I finally felt better about it mid July and since then have overall been feeling great. He reached out to me over the weekend sending me a text wanting to apologize in person. He owned up to his actions of slut shaming me, and saying how he could have tried a lot harder in the relationship. He was absolutely shaking. I was tough and strict with him and kept details about my life to a minimum. He then told me a few days ago he broke up with another girl. And I said I am sorry? He then said how he regrets things and the way that they ended and that I am the best he’s going to get, and he slept around a lot until the breakup probably hit him mid July and he started feeling sad about it wanting to reach out. And I said wow that just when I got over it. (We are in college by the way). I told him I respect the fact he manned up to apologize to me but I shut him down completely with getting back together. I said I wish to be amicable and to be able to say hi to each other on campus without it being weird. I felt no feelings at all. Only like a past self was being recognized but I have grown so much for the best without him in my life and he really brought me down. It was definitely closure, but all I can say is that you need to truly be over your ex to be able to amicable and friendly. I was happy we were able to talk things out like two mature adults. And its very true about the difference between men and females the way they process breakups differently. Right when he regretted it, I was envisioning myself finally seeing other people and feeling like myself. My friends say he was clearly testing the waters to see how open I would be to getting back together, and at first I disagreed but now thinking back that was very true, but am so happy I shut him down. And today we walked by each other and waved. That was nice to be civil I will admit.
