What do you guys think?

My ex was abusive af he beat me. He would always call me out my name. Put me down. We were together for 2 years and we broke up 4 months ago. I finally had enough and left. I’ve been to counseling and such. I cut him off completely. But I was never able to cut him off on instagram because he had blocked me which made it hard for me to find him and block him. So what he would do is unblock me and watch my page and comment or dm me on how I would look in my pictures. That my pictures look “weird” or that “you never used to look like this when we were together” and then he would block me again. I would never answer him I would honestly just ignore him. Before he started doing that I would get emails now its DMs... why does he keep blocking me but unblocking?

Honestly I don’t go on his page I don’t wish to see him. I feel better now that him and I are apart.
