Well Chiefmac88,
From what you have typed, I'm conviced that you already know that you can't have her. For that matter, that is the exact reason you're having a hard time getting over her. Everyone wants what they can not have, sad but true for almost everybody.
She flirts with you because she knows you like her, it is a confidence builder for her. She sounds like an attention wh*re, if you ever got with this girl she would prolly crave attention from the next joe while dating you, you wouldn't want that now would you? When she flirts with you, what do you do in return?
You don't get out much but your sociable? That's really not possible if you don't get out much, think about it.
Impossible is a word only to be found in the dictionary of fools.
