Most Helpful Girl
She forgot... right. I don't believe her.
Maybe she's like seeing more than one guy (online it's even more common I guess)? And she forgot what you looked like so she wanted to see your pic again to see if she liked you or not? Who does that?
From what I read I think she wanted to get to know you, but why did she refuse to do it in person or at least by phone? It's so much fun to talk to someone by phone why wouldn't she want to do it?. Maybe she just likes the attention, don't waste your time on her.
Sorry, if it sounds harsh.
