Hey pilot, I would also see this as positive. She didn't reply to your text but maybe she just didn't know what to say, or maybe she got busy... or who knows!
Look at what your DB coach's advice was:
"She does not want me to get stuck in the friendzone and we want to keep any positive movement forward moving forward. No stop and go stuff, as it would only build confusion for a W who does not want to lead, but follow. "
So don't get all crazy and change your tactic again now. Just keep trying a little bit. Don't be pushy but just keep being friendly with a slight flirtiness thrown in for confusion.
