please please please tell me you did not send any of those messages to her. be patient, sometimes it takes a bit for people to respond. besides, the longer you take to write or respond to her, the better.
ok, i agree with pretty much everything kasabi said. Except i would not ask her to go some place, i would tell her where i am going and say she should meet me there.....
example: "Im going to the mall tomorrow at 2. You should meet me at Express so I can give you some fashion tips

"
You don't need to bring up the BF one bit. She didn't put the shit up about her BF specifically for you. She did it for her BF. You showed that you are jealous needy and insecure. Next time play like the BF doesn't even exist.
If she even sends you a message back, play it cool. Honestly, its time to move on.
EDIT: When you were told she thought you were cute, she could have just been looking for that male attention that she is missing since her BF is outta town. It doesnt necessarily mean anything.
Good luck bro,
CK
