Boy to man advice please!

My son is 13, soon to be 14, and it feels as if he is refusing to grow up. He remains attached to me and I feel awful when I tell him he needs to break free and become more independent. He seems to quiet down but reverts to the same needy state. He will not make decisions for himself and I am simply at a loss when he just sits around waiting for me to give him direction. HELP!
