So Called Bestfriend

I am a girl his a boy and we're bestfriend, I love him more than bestfriend and he doesn't know that. One sided love ? No its not I just don't want him to know what my feelings is. Because I'm scared for his rejection ? Yes I'm scared not because for his rejection I'm scared because I don't want him to feel pity for me just because he can't love me back, I don't want him to avoid me just because for what i feel for him. I'm ready for the pain I am ready dying everyday for my feelings.
