Why would he try and mess with me, while I told him I moved on?

I'm here, left with a question that can't be answered. Though I'm curious to know what could have been the mindset here. There was this guy I really liked, and I remember he fooled me by him telling me he liked me. Time goes on. Nothing was going nowhere. Literally, he came over to have sex with me. Cuddle me. Had trouble just getting a response from him sometimes, because "work was overly busy." Bullshit cards. I got ghosted.
This ghoster comes back in my life, feeling absolutely bad for letting a good girl go. He was devestated, I guess. Telling me how much he let a good girl go. That he thought of our chemistry around the holidays. How much he missed our movie nights, this and that. Again, nothing ever outside my apartment. Constantly begged me for second chances.
After he ghosted me, I never viewed him the same. He ghosted me through a time I was going through personal obstacles that I later jumped. He knows this.. Telling me he "felt bad for thinking he ghosted me." Yet I smacked him in the face in text, saying he did ghost me.
I couldn't handle him anymore. I knew things weren't going to work in the long run. He gave up on me. Lot of me let go of him. I knew I was a very good person for him. He just never tried, and it SHOWS. He was emotionally unavailable, and he tried to hold me on.

A few days ago, he added me on Snapchat. Deleted me, and I thought... I told this guy that I found somebody, because I have. WHY is he trying to play this game with me?
Did it get my attention? Yes. Am I going to reach out though he's blocked? No.

GUYS. I KNOW THIS IS DUMB OF ME, BUT I'VE LEARNED A LOT FROM THIS RECENT PERSON. ONCE SOMEBODY GHOST, YOU CAN'T CHANGE NOTHING.

Thanks!
