My memory is just weird. I can remember useless details, like old phone numbers or the birthdays of people I went to high school with and haven't seen in 40 years. But I'm bad with names, and sometimes I "lose" people when I meet them out of context. Once in the grocery store I ran into a man I had served with on a condo board. I knew his face was familiar, but the context in which I knew him, and his name, completely escaped me. He politely re-introduced himself to me and I wanted to sink into the floor. And emotionally loaded memories definitely go AWOL, but again, selectively. I remember some of the awful thihgs I said that ended a relationship, but not all, and I have no memory whatever of what my partner said that triggered me. My short-term memory isn't what it should be either. Some of this may be just aging, but I suspect that "BPD brain" gives age a head start.
