How to move on

There’s this guy whom I work with, he has blocked and unblocked me several times. Every time he blocks me the reason is he thinks I make him feel sexy and then seeing me he just thinks where to put his hands on me. We both know that this all has no future, or we don’t have any future together, yet we like to be touched by each other. But This time he didn’t block me bcz this time when after one month of unblocking we were normal in the beginning but then again somehow or the other sexting started, though I stopped but it was already very late. Since it was night time, he promised me he won’t block me and asked me to sleep peacefully but the next day he deleted my number and told me that he doesn’t want to talk to me and since then he is not replying to my messages.
I am so much stressed. I don’t understand what to do? How to move on? Please help
