Does he really like me or what?

So this guy at school in my class pays a lot of attention to me... i have a crush on him, but.... its weird. all of my friends say this: "everyone knows that jack likes valya exept for valya herself"

he always acts weird around me, sorta showing off... we have a Word for us, 'frienemies'

whenever i catch him looking at me, he sorta stares and then looks down. but why would he like me?

ps im not ugly or anything, im lean with wavy hair and im tall, hes cut- to me
