Why does he keep coming back into my life?

Anonymous
This guy and I used to like each other, but for some reason (which I still don’t know), things went downhill and we stopped talking and he cut me off. This really messed me up. Now, whenever I feel like I’m really letting go of the situation, he pops back into my life and it’s back to stage 1 of moving on. This has happened about 3 times. I’m starting to question, is this a sign? If so, what am I trying to be told? Ideas? I’ve tried asking him what I did but he didn’t tell me, just left me on read.
