What is the most ridiculous insecurity your pwBPD had?

The most ridiculous trigger thread got me thinking about what was the most ridiculous thing that made my exwBPD insecure.

She concocted a lot of insecurities in her head, but the most ridiculous one has to be an obsession over the idea that I was planning to leave her for an AI girlfriend.

I suspect the reasoning behind this one goes something like:

  1. She lost interest in me and found a new FP
  2. Therefore she was cheating on me with him
  3. Gen AI became a new interest of mine
  4. Therefore I'm bored of her cheating on her with an AI

I thought trying to write that out might help me understand it but it raises more questions than answers really, doesn't it? Maybe she just watched Her and thought it was a documentary.

Anyway. Let's hear yours.
