possibility but... if she were that interested she'd make time?
My apologies, I'm usually optimistic, but with the teensy little exception of pessimistic towards women -- frankly I have yet to find one that impresses me that much.
I'm in a similar boat right now -- message a girl, no message back, what the hell does that mean?
Hell if I know, but you said you've talked to her in the past? I'd say she's waiting to get back to you. Just a hunch, but women usually prove me wrong. Just, dear god, don't flood her inbox with 500 messages
And then if she never gets back to you *shrug*
