I'm always suprised - my BPD wife often tells me that "she can see I'm feeling X" when I am not. I have read somewhere that they find it hard to pickup on other people's emotions - which suprises me because I thought they'd have to be really good at it to manipulate people so well. (Although they aren't very subtle with emotion, so maybe not). My wife also calls me an unemotional robot - because I don't allow her to rile me up - but she doesnt see when I cry with the kids, or am super excited about something.
Interesting. That was another aspect of our relationship. My wife believes she is an empath, and she was constantly physically and emotionally exhausted from taking on the emotions of others. Toward the end of our relationship, when things were disintegrating, she told me she though I hated and resented her. Neither was accurate, in fact quite the opposite. But her response was, "That's what I felt."
And I give you a lot of credit for remaining calm, ArleighBurke. That was perhaps one of my failures as a husband to her.
