If He is that amazing, if you are sure he is straight, and if you think he'd be okay with it, tell him how you feel! Life is too short for regret and wondering later what if. You must be prepared for him to possibly freak out and break off the friendship. But again, if he's that awesome, and handles it well, are you prepared to love him from a distance, knowing you'll never be together. Only you know what level of emotional intensity you can handle. Go for it!
If he's straight. Then he's straight and there's nothing you can do about it. So friends will have to do. If not, then good luck.
Find a boyfriend, that's what you do.
