Now I know you guys love to think that your one acronym advice has actually helped someone for once, but actually...
I asked her to hang out, and thanks haha
Technically she said "yeahh maybee;)"
GOOD ENOUGH.
I gave her my number. Now all I gotta do is wait.
So let me get this straight: you asked on Facebook if she wanted to hang out some time, she said maybe, and you gave her your number, to which she hasn't responded?
Now, call me a cynic, but I'm not even sure that necessarily constitutes "asking her out", let alone successfully. At any rate, even if you think it sounds like a request for a date, she easily might not have understood it that way. And whether or not she did, her answer was
veeery non-commital, and much as the sixism in this thread is as lame as always, you probably need to get her number before you can decide either way.
Given how ambiguous online communication can be, and how little attention people sometimes pay it (and she sounds like one of these people), stuff like this is always gonna be easier on the phone or face-to-face.
EDIT: Although maybe it wasn't so ambiguous to you. Without seeing the whole conversation log (and it'd be a little creepy of you to actually post that) it's hard to tell. If you're confident enough that it was clear then go for it I guess.
