So I made plans to hang out with a girl last Thursday. She flaked, and suggested we hang out the day later. I told her I was going to a friends birthday party, and that she was welcome to join me, and that we could hang out before we leave for the party.

I texted her on Thursday saying see you tomorrow, and we briefly talked on the phone. I didn't hear at all from her on Friday, and assumed she flaked and that it was a lost cause at this point. Got a text from her today, saying "Do you get back to people? You left me waiting on Friday. I guess we're even now."

I suggested she come over this Thursday, and she said she would love to but has plans. What's the best way to go from here. Should I just send a text asking when she's free? Should I ask her out on a specific day and maybe have her flake? Or should I just not text her untill she texts me. I get the feeling she is still interested, because she wanted to go out on Friday, but thought it was a little childish not to text me if she was waiting for me. I guess it goes both ways since I didn't text her to confirm.
