Hello SadArtith-Medic, welcome to the group. Glad you reached out for support and understanding at this time.
It's good you're able to see some areas where your actions may have contributed to her feeling hurt. While "broadly normal" people can typically discuss feeling hurt at eyerolling etc, and then move on, highly sensitive, emotionally volatile people, such as pwBPD, may hang onto that incident and/or experience extreme distress. That's not to excuse her behaviors, more to offer an explanation that pwBPD can be extremely sensitive and reactive to things that generally normal people can process and move past.
It makes sense to give both of you some space and time to cool off. It wouldn't surprise me if she were open to reconnecting -- what did that look like last time she blocked you, how long did she seem to need after that?
One more brief question to understand your situation more; you mention:
I don't even know if it was her BPD or if she was just sick of me...
does she have an official diagnosis of BPD, or more traits/behaviors but no diagnosis? What led you to suspecting BPD at play?
Let us know how the last few days have been for you;
