Actually, from a girl's point of view, I think she sounds pretty genuine.
I know what she means about worrying whether she'd live up to expectations - I'd say it honestly is hard to overcome those kind of feelings and decide to meet up someone, who expects you to be great.
However, the fact that she says your attention has been "flattering" and then nothing more on the subject made me think she doesn't want you as more than a friend, sorry.
She's taken the time to reply properly to you - she sounds like a good friend.
I'd give it a long time before asking to meet her again if you still wanted to - I don't think she'll change her mind in the near future.
