How can i forget about her when she's too special?

I think it's time for you to sack up sir. Tell her how you feel. If you don't tell her then she will never know. Be completely honest with her and don't hold anything back. See how she takes it and if it totally changes your relationship then you have to know that is a risk you are willing to take by telling her. You only have one life and if you like her that much then tell her how you feel. Don't let her get away. She may think it's just a game but she may soon realize that she likes you back.
