Hello, friends.

I'd been trying to make a relationship work for years with a woman I now suspect has mild uBPD, and she and I finally came to the conclusion that we had to end it. (If you want details, we'd been trying to make a polyamorous relationship with my wife work, and my ex decided to end it, and I decided that it was indeed, for the best. Neither of us wanted it to end.) She wanted to meet one last time to find some closure and I was struck by what she brought to the meeting:

A boxful of mementos collected over the course of our relationship that I'd never noticed that she had- The foil wrapper from our first bottle of wine. A lime rind from the first gin and tonic I made her. A note that I'd written on a piece of trash that I'd left her while we'd been broken up, a popsicle stick stem from a trip we took together, a necklace of hers that I'd accidentally broken, and so many more. No woman I'd ever dated had ever done such a thing in honor of our relationship and I was deeply, deeply moved.

But then I read somewhere that this might not be uncommon behavior for people with BPD. I'm wondering how many of you have experienced similar behavior with your pwBPD? If it's a BPD trait, do you have any ideas what might cause this behavior, or how this behavior might relate to the BPD psychology?
