Of the couple of people I've known who I strongly suspect have BPD, they both had a tendency to write long-form, hand written letters.

One of them wrote a three-page love letter to a situationship that was (from my perspective - her friends literally nicknamed this guy an addictive drug) clearly her FP, and when he responded to it with basically "sorry, still just want to be FWB and nothing more" she came back the next day and said that was totally fine, she didn't feel any of the things in her letter anymore and was just being silly, and could they please continue their situationship.

I remember being really struck at how unusual it is to write a three page love letter to a three-month situationship to begin with, much less to have such a dramatic shift from its contents within a day.

The other person I suspect had it would do more frequent, shorter but still flowery, seemingly sweet letters to their partner in between the times treating them like total garbage.

So is letter writing in this way a frequent or typical thing with those with BPD?
