Why did he unfollow me?

Somewhere in August I hooked up with this guy. He did make sure I got home safely then it was awkward so we stop talking. I messaged him sometime after, he responded quick and we talked normally, but I felt being treated as a fan (maybe it’s in my head cause I prefer men chasing me, not the opposite). I assumed he wasn’t interested in me. So we haven’t spoken ever since. I did post before occasionally of course, but this time I posted a selfie (me in a dress), I got whole bunch of guys going crazy but him... HE UNFOLLOWED ME AFTER SEEING THIS.

Yeah I understand, he didn’t like me but still he didn’t have to remove me, it did break my heart a little.
