She left me hanging!

I called a girl a bit ago that I'm pretty sure is into me (we farked last weekend, I f-closed her, and she has been talking to me a bit here and there since) and asked her if she wanted to go get a bite to eat and see a movie tomorrow night, she said she might be going to this party, so i said alright well let me know, give me a call tomorrow, she said okay.

is she playing hard to get, should i expect her to call me back tomorrow?

if she doesn't what should I do?

I am definetly no expert, but my observation is that most women will not say no to your face but come up with vague excuses with no follow up offer when they are not interested...but then again maybe when she said she "might be going to a party" she was setting you up for you to ask to go with her? ie. "Oh? Can I volunteer to be your arm candy?"

Again I'm no expert, but what did happen?

you may also want to consider the possibility that her plans ARE full atm, give it time. usually as a rule, if shes passed up on hanging out with me 3 times over 3 weeks, shes flaking.
