Smear campaign?

Somehow I keep coming back here. Maybe in the hopes of processing and understanding.

After the last contact with my exPwBPD a few weeks ago, twisting everything, making me seem the bad person, blaming me for everything, claiming that I was harassing their family etc I did nothing. Didn't contact anyone. Just discussed with my own therapist and friends.

I reflected on some of the things she said to me about how she is and noting her parents said to reach out if anything happened again, I looked at their contact only to find out I've been blocked. Not by the whole family , just one that I had spoken with and who was very supportive to me.

Given that my ex had an uncanny ability to k ow just what I was discussing with their family, I wonder if they blocked me rather than their family, as it would be very uncharacteristic for their own family to block me when I literally sent them condolences for a bereavement and they had been on my side the entire time. Tbh, having this hurts more than being ranted at by my ex. Am genuinely puzzled. And I've only been blocked on the main method we communicated. My therapist said my relationship with them was independent of my ex and their own family agreed. While I get one has to move on and let go, I did see them as a second family and all our correspondence was saying how I didnt deserve anything that happened to me. So I'm very stunned.
