Clueless? No I think I'm Oblivious

Okay so anyone who reads this knows its about a guy. Know how can a guy not know you like him? How can you not know if a guy likes you? What happens when everyone thinks he's dating your best friend? I've got the ansewer nothing! So I've liked this guy for the past year and a half. He's only known I exist for the past year. Our friends have been trying to set us up for half a year. We have gone out a total of zero time. I hate high school!
