It sucks when these things happen but they do. Just means there's someone out there that's better for you and this wasn't right.
That wasn't serious. ^^ Maybe she really has feelings for you, but she doesn't want to show them because it might ruin the friendship. Have you tried reassuring her that even if you guys don't work out, you'll always be friends? If she says no after that, it probably really is because of the first reason.
If it's killing you, you need to avoid her at least long enough to get over her. As said, if she's always around it's not going to change. Although if you're dead set on trying and you're good enough friends for the situation not to be awkward, just ask her to do things as friends and hope something clicks along the way for her.
Don't do what Doll said Cause anything that falls breaks (Saw that somewhere lol) Just man up and tell her. DO IT SON!
From reading this I conclude that she's into BAD BOYS. So to win the heart of said damsel you must Get into some trouble, rob a bank, step on Obama feet repeatedly, or something. This will make her ovaries ACHE FOR THOU. Deuces.
