Also the "Hit me up when she wants to hang out" doesn't seem like a great move either, that may just be my opinion. Same as above, it gives her way too much power over when you guys will meet up. I'm not a big fan of the whole power games thing, but those seem a little too soft to me.
To be honest this girl seems like the kind who thinks she's hot stuff. I would stop texting her, at least for a while. Hit her up randomly a few times and see where that goes, but honestly I think it is better to proceed with other options at this point.
