I actually did back off. I actually referenced this article

For whatever reason getting this chick on the phone is impossible. So whatever, I send her a text that says something like
"yea life is busy for sure. If you want to meet me lets set up something definite in the next couple weeks. If not, we can go our separate ways."
I get a text right back
"Hi XXXX, lets do Thursday if you're still available. But I totally understand if you do not want to. My schedule has been inconsistent over the break. Let me know if you still want to"
I respond 4 or 5 hours later saying:
"Sure, Thursday is good. How does 7 at xyz sound?"
She immediately responds
"Great! See you then!"
So there you go, will she flake? Who knows. But if she does, obviously its next after all this. I do think the "i have no problem walking away" mentality spurred her into gear. And really, I don't really care at this point, which is a powerful feeling!
Will report back if said date actually happens, and how it goes.
