This is such a difficult situation. I think she has decided that the distance is too far, or you aren't what she wants right now. You won't be given a lot of opportunity to really change this around, so you will have to be creative if you want more chances. I personally avoid trying to get most girls that suddenly change their act. Makes me think they're hiding something, or they're bipolar or something like that. If you need some ideas, I suppose I can help you out with one though that will give you some fighting chances! No promises though,
Text her saying something like, "alright baby I'll be there in a couple minutes! You're ready to go right?" Her response will be some indication of confusion like, "What? What are you talking about?!" Then you could be like, "we're booked for a fabulous Hawaii vacation for two!" Then she will most likely send some kind of cynical response like, "uhh no." Then you say something like, "Hm well then instead how about coffee on forest ave?" (or beer, or whatever). That could very well get a good response.
The point is to undermine her opinion of you as a needy attention seeker, and then surprise her with the reality that you aren't.
Either way, don't let it get you down if it doesn't work out, you are obviously a good PUA, and with practice, the fish will stay on the line longer!
