Everybody feels this way about their crush - that if only they got to know you they would realise how perfect you are for each other. This is not the case though, especially if they don't even know you exist. Besides, I guarantee that even if you do get to know him there's the chance that the fantasy of him won't live up to the reality.
I do think you should put yourself out there though, you say you are not friends so initiate a conversation and see where it goes from there but be prepared for the fact that he may not reciprocate the feelings you have for him. Just because you feel so strongly and intensely for him does not immediately mean he will too. Work on building a friendship first.

Love is like a merry-go-round: you get all dizzy, and then you feel sick!
