Do I add my teacher on facebook?

[.]

I just graduated high school and I wanted to know if I should add a teacher from my school onto my Facebook. He taught in one of my classes or helped out and then I left to do online school to catch up before coming back to graduate. So I barley had him as a teacher. I'll get to the point though, he's super cute. Not even going to lie! I don't want any relationship from him though, I'm moving anyway. But! I didn't know if that would just come off totally weird or what. So your options are much appreciated, thanks!
