So I met this chick only once, got her number over fb (she initiated message and sent her number without me asking) and have been texting this whole summer while I was away working. I recently got back and have tried three times to hang out and it hasn't worked. Here's the last text convo:
Me: Sooo I got a question

u able to see r movies? (she's christian)
Her 3 hours later: Hey I'm so sorry I didn't respond! I was swimming with my family. Yes I watch rated r movies haha

Her again: Hey! I'm completely free on Thursday. Wanna hang out?

Her yet again: Just kidding I'm actually completely free on Wednesday too!:)
This is the third or fourth time I've asked her to do something in a way and she always has some reason not to respond for a while or not go. I want to just give up... any help on what to say/do?
