How do i get a guy two years older than me to like me?

so i kinda like this guy and my family knows his and he knows my family too. i started to like him a little while ago and he's like the sweetest, awesomest person you will ever meet. so we've talked on facebook a little and i like him, but no so much the next time i talk to him i'll pour my guts out. but it would be nice to have a guy to actually finally like me for once. i'm a freshman and he's a junior. no rude answers either, cuz i really don't care what all you haters have to say.
