Is it normal to still want him

So here's the deal. First of all I am a gay guy in high school. I have known a boy since my freshman year and he has always been fun to be around. It wasn't until sophomore year that I started becoming attracted to him physically. Later on I find that I have become attracted to him in a way that goes past superficial reasons. Im attracted to his personality and who he is as a person. I think about him constantly and since I'm a performing artist I've even gone to lengths of writing a song about him. I see him everyday and I can't tell him how I feel for fear of ruining our friendship. I think I might be falling in love with him. But the killer of the mood is that he is straight. Here's a twist to my dilemma. Another one of my good friends has feelings for him as well and for a year longer than me. Should I let her have him and ruin my happiness indefinitely or go for my shot and risk a friendship. I feel I should do the right thing because it could never be but I still want him.
