Hi LL and welcome
She wrote that she has never had such a strong aggressive public reaction in her life and that this scares her.
PWBPD are known to lie; really what occurs is they make up their own reality to fit their current emotion of the moment-to them feelings=facts, and it goes for the past, present, and future. Be very careful what you believe; always best to go by their ACTIONS, not their words as I'm sure you have experienced.
While you are learning about BPD, taking a break from your relationship (good thinking on your part to be hesitant to meet with her so soon), I would recommend you compare all of the good vs. the bad in your relationship: some find it helpful to write everything down for comparison.
If you decide you want to continue to try and make it work, I would say it is essential that she commits to years of therapy (ideally DBT) and you are willing to apply the tools needed, and sacrifice your needs, to manage the relationship.
