You 2 arent dating. Sounds like she likes to text you stuff to get you going with zero follow through. If you two are in highschool i bet she is showing her friends the texts between you two and they are laughing at you. Sorry but i think she has discovered her "sexuality," can be used to waste guys time while keeping herself (and her friends) entertained.
Withdraw all attention. Force her to reach out to you. If she doesn't then you know she was just wasting your time and luckily you only wasted 2 dates. If she cares, she will reach out. Then when she does, make her put her money where her mouth is. If she yanks you around again, you hard next.
