Do we stand a chance? In NC now

Hi fellows,

I broke up with my ex a month ago. We were together for 2.5 years – 1.5 years in long-distance and nine months in my city.(I wanted to clarify that he didn’t move to my city for me, but for a new job).

We had fights quite a lot, and he didn’t seem to be very committed other than being exclusive. We could never agree on the issue of living together or not. He never wanted to do it now, but I felt insecure so I pushed him hard every time. We had two big fights before about this issue.

There were signs about his uncertainty. Last November we agreed to visit his hometown for Christmas, but a week before we broke up, he told he didn’t think it’s a good idea anymore. He also stopped telling strangers that he had a girlfriend, leading to girls asking him out.

My mistake was that I got very offensive whenever I was angry so he couldn’t take it anymore. He avoided talking to me for three days, before telling me that he wanted to be friends. After that, I told him I respected his decision and started no contact (for four weeks now). During the first week, he messaged me every morning and even asked to hang out. I told him I need time and space, he replied that he knew, but he missed me and was worried to lose me.

During the second week we saw each other accidentally but I turned my head because I was not ready to talk. A day later he texted me and said that he was hurt, to which I didn’t reply because I stick to the NC rule.

Do I still have a chance? He didn’t text me anymore after these two weeks.
Also, how should I show him that I have changed? I am usually sweet and only became offensive when I am angry, so if he goes out with me again, he won’t necessarily know that I have changed. Do you have advise for me?

Thanks a lot,
Beany
