I like my teacher...and now i am graduating..what do i do?

okay so i really like this teacher....i know its weird but i cant help it lol..and idk somewhere i know it feels right. I am graduating next week..i have no idea if ill ever get to see him...what do i do? oh and i THINK he like me too! but he kind of keeps it discrete cause i guess its not right for a teacher and student to get involved? ...but hey i am graduating now and i am 18...he's 26. should i wait for him to make a move and see if he likes me? or should i do something about it? p.s. i really like this guy :(
