How do I tell this guy I like him without it being so awkward?

Well i am 16 and i went through all of that, my advice is to as him to hang out with u for a day like watch movies at his house or, at your house, or have your mom or dad bring you to the mall, but don't go to the movies because then you cant talk, you want to talk to him and ask things about him and he will most likely do the same to u and some things to looks out for is if he always smiles when hes with u, he tends to stand close to u or sit close to u, he might fidget his finger(not all guys do that) but most guys try to look cool in front of girls they like by making a scene or something, but i really suggest hanging with him for a while and talking and maybe he will ask you out, but i wouldnt tell him that u imagine growing up with him because that would scare him away, but DONT ask ur friend to ask him out or anything it just makes u seem shy, guys like girls that do it themselves TRUST ME!! i went through this, the good and the bad, i know what im talking about lol. well good luck and i hope i helped a little!!
