Ran Into ex-pwBPD Today, 6 Months Later

The short version — I ran into my ex on the street. First time I've seen her in almost half a year. A bizarre experience. It was her and "not her". She was so familiar and yet so foreign. I stopped walking, took off my sunglasses, said "hey." She did not acknowledge me. Only her tense, angry, confused affect showed any sign she perceived me.

It was mutually...ghostly? It was as if she could not even see me...and she herself was so...unreal, if that makes sense. But I was proud to see myself so composed and walk on without further reaction.

Long version - Was in her neighborhood to resolve an issue with an office we had rented together. Essentially, after the breakup, she split hard, insisted I was "evil", a "psychopath", abused her "daily" for six years, etc. In that state, she did not allow me to go to our rented space, even though I was still paying half the rent for it. As the lease came to end, she had reached out to ask if I could pay for movers / scrub the outside. I was open to help, of course, but I wanted to talk on the phone about it to be both thorough and, admittedly, to break the absolute barricade and reclaim some semblance of humanity after so much vicious slander and dehumanization.

Naturally, she declined. Our communication over logistics faltered over the next month. By the time it got to move out day, she declared she would take care of it all on her own and shut me out completely.

Five days ago, landlord sends us a rightfully frustrated message via group text about the space, which has been left in "unacceptable conditions". We will have to be responsible, rightfully, for the damages and mess. Now, hilariously, landlord cannot send this message to us as a group as I am blocked...so she sends it to us individually. lol.

To not throw ex under the bus, I get in touch with her via email & the only unblocked app and wait for a response before engaging directly with landlord. No response. I get in touch with the landlord that evening, take responsibility, assure her I will do my best to fix what I can and pay for the rest. She is assuaged. I check in on Sunday to ask if she had ever heard from my ex, her paying tenant...nothing.

Today I go there to see what can be done. Take pictures. Make a list. Send update message to ex with a list of to-do's asking if it's possible for her to do her part here and make sure we don't incur more fees. Of course, nothing.

So then, walking to the bus stop, I see her coming out of the grocery store. First time I've seen her in almost half a year. A bizarre experience. It was her and "not her". She was so familiar and yet so foreign. I stopped walking, took off my sunglasses, said "hey." She did not acknowledge me. Only her tense, angry, confused affect showed any sign she perceived me.

It was mutually...ghostly? It was as if she could not even see me...and she herself was so...unreal, if that makes sense. But I was proud to see myself so composed and walk on without further reaction.

The words I would use to describe the interaction/non-interaction are "bizarre", "eerie", "disconcerting", "strange." I've read up a lot these past months to understand what is going in a mind like that, but seeing that detachment—specifically in the face—is an indescribably unsettling experience.

Have any of you had experiences like this?

As always, thank you for your attention and generosity.
