I met someone last year and became friends. We liked each other and it was completely platonic. What is this?

try to talk to him, he myt feel the same way. if you run away its still going to be there when you get back. Jus try and talk to him, if it goes horribly worng then atleast you tried and you don't have that person in the back of your head saying 'what if i tried to find him'. Dude if you love him then don't stop at anything until you get him. Good luck.
