Here's the deal: You have no control over the outcome. The ball is in her court. She is now measuring you up to her other offers, including her personal trainer. I'd just start seeing another girl if I were you. She may have just wanted some attention that her boyfriend wasn't giving her. Don't text her again until 11 days later unless you want to show desperation (or if you do, text her you started dating a better woman.)
It's all about her interest level in you. I won't use the celebrity maxim here, but having a woman into you until you ask her out, then she starts running away? Bad sign. She's upset knowing she's gonna lose a source of attention, but will be over it when she gets railed by that male gym rat.
Erase and replace this girl. Replacing this girl may be a chore, but if you can actually replace her, not just erase her, you'll be all better.
Case closed.
