So....there's this guy......?

I've liked him for a pretty long time now. Hes a year older than me so we really dont hang in the same social group even though we really do have a lot in common. I had a cl with him last school year and ever since then i havent stopped thinking about him and i figured it was just a crush and if i didnt see him all summer it would go away. well it hasnt. Ive seriously never felt this way about a guy before but its so intimidating because hes just so outgoing and i feel like he probably has more options other than me. I havent ever felt scared to talk to a guy before. im usually not the shy one, but hes different. hes so cute and like the funniest person ive ever met in my life. The thing is, i feel kind of weird just striking up a conversation with him now because i havent talked to him all summer. I thought about mesaging him on facebook the other day, but couldnt bring myself to do it. Someone please help me!
