What’s up with this weirdness?

so there’s this guy who I’m pretty sure has some sort of crush on me. He’s constantly hanging around, I catch him staring at me and he does things to get a reaction out of me. Him and his family members are always staring at me. Under no circumstance does he make an effort to engage with me though. I get the sense that certain behavior is expected of me but I am not providing it.
