I would turn down any future invites to get together.
You definitely do not want to jump at every offer. You also want to switch who is in control. She is in control at the moment.
First time: I get a text from W at work last week, “Want to meet me tomorrow night at xxx?” Needless to say I was shocked. I waited 4 hours to clear my head and responded “Sure”.
Second time: I get a text from W “Want to meet me tomorrow night at yyy?” I wait 6 hours. I respond “I can't. Already have plans”.
Third time: I get a text from W “Want to meet me tomorrow night at zzz?” I respond “Already have plans”.
At some point, you can respond with "ABC works better for me." or a boundary "when you wait until the day before bla bla bla ..." or you can decline every invite and wait until she comes begging you to take her back because she made a mistake.
