I lied to this boy and said ''I like skateboarding'' then i told him the truth and now he probably hates me Iv'e been sending him letters and you are to shy to tell him that i like him?

Oh man. This guy most likely wont care if you lied about liking Skateboarding. He probably cares less about that. Just tell him how you feel about him and hope for the best. You can never be scared in life or you will always wonder "what if". And if you ask me wondering "what if" is alot worse than being rejected. Just believe in yourself and be confident and keep your head heald high no matter what happens. You can do it! PEACE~!
