Should I be worried that she didn't message me back?

Ok, don't freak her out with all your flirtiness, because she probably is thinking that your one of those clingy types. If she really likes you, then she would have messaged you back or messaged you first. But theirs that possibility that she's busy or something. I think you should wait a day or 2 to message her back, and then when you message her be like "hey, how are you?" cause you don't wanna ask her out right away and her give you some lame excuse to not go. Have a few normal conversations with her first, and figure out her personality a little better.
