Now you do nothing for 48 hrs. You have been letting your and her emotions drive you.
Now is the time to stop this cycle and start letting your rational thinking lead you.
Wait 48hrs to see if the crazy train comes back around. Again she probably got dumped from OM and is just feeling lonely. Do you really want to be the backup plan.
For now. I would not REACT to anything she has says. Just let her know you appreciate her talking to you and that YOU have a lot of THINKING to do.
