Do I tell him I love him?

Ok there is this really great guy. I've known him for 2 years or so. He is my best friend in the whole world and I want to tell him I love him. He is just so perfect at everything he does. He's great at music, smart, funny, and his name is Matthew. I know he thinks I'm a bit too clingy and a bit of a creep. I think he likes somebody else who I desperatly hate. What do I do? I want to tell him I love him and I'm not much of the kind of person who just says "hey I love you" out of nowhere. I;m so confused and in need of serious help. Please I've looked everywhere to find some sort of help and everything I found just failed. Please I need some help.
