Is it weird falling for someone at a young age?

Well, I asked out my friend a while back (4 hours) and I just felt like we needed to be “closer” so to speak. (Not in that way.) We’ve known eachother forever and he likes me like I like him.
So, when I asked him, he said yes because you’re sweet, very nice, and very cool. But he also said no because he doesnt like my friends that much.
I guess I’ve kind of fallen for him now because I can’t stop thinking about him. I like him soo much. My question is though is it bad that he said both yes and no? Should I change really anything about myself? Is this weird? He’s just the perfect guy. Am I asking the right question? Am I crazy?
