I ended things before I catch feelings, he said he misses me then ghosted me but keeps on checking my socials why?

I was seeing this guy, from the beginning we both said neither one of us wants to be in a relationship so pretty much friends with benefits. All was going good, two months and we went for a weekend gateway together after we came back I realized I will eventually fall for him because there is something special about us comparing to others. He was always saying our sex and time together is very special but I assumed he was just saying what I want to hear. I decided to be honest and end things before I catch feelings. Sent a text with explanation , he wanted to talk but didn’t make it when he arranged. After few days he messaged saying he needs to admit he misses me. We ended up having a chat over texts and I said I’m scared to fall for anyone due to my past. He then ghosted me but kept on looking at my stories as one of first people, I assumed that’s by accident. Then he started liking any picture I post... like wtf is going on in his head? Why can’t he just disappear if he ghosted me
