I Helped this girl who completley ignores me and yet shes still not all that friendly with me?

Why? Let's see that person she likes stalks you sometimes, follows you around and stares at you instead of HER. If you liked someone and asked a friend to ask him out for you and instead you see him be interested in her instead of you, what's your reaction? "Oh, yeah whatever he likes her and not me." Got the idea? :-)
