<human>: We dated for 7 months. Two months ago he broke up with me. No matter the reason, the relationship wasn't healthy for me, even when I still love him a lot. The first month I tried to contact him, but I got not answer. I have to admit that I was doing very good and it wasn't affecting me at all (compared to my previous break-up 3y ago)

A couple of days ago he contacted me (because of my birthday) and it was like nothing happened. We texted and I realized I don't want to keep in touch anymore because I felt like he was part of my past and there was no chance to have him in my future, so the next day (last Thursday) I decided to give closure, and now I feel terrible. I don't regret doing this, but it's just that I can't understand that he is never going to be part of my past anymore, and I don't know why I can't get the idea of that, if I know I need to do it in order to move on.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I don't have a particular question, but if you want to give some advice in how to feel better, I would really appreciate it.
