What does this indicate?

3 months ago, I hooked up with this guy and the sex was amazing. we chatted a little bit and then he went along his way. he definitely searched up my Instagram and checked me out after our hookup bc I saw he watched my story.

a week later, I decide to hit him up with a “wyd tn” text and he responds saying he is at a short event, so naturally I ask him if he wants to come over later but he doesn’t respond and the school year ends so we cease contact.

just recently, he started following me on Instagram (he never followed me immediately after the hookup) and schools about to start again. Do u think he might want to be fuck buddies?
