Agreed. As I was reading the comments I felt the same anxiety I get when I talked to my gf who displays symptoms of bpd. It was like I was dealing with the same frustration of how she responds to things.
As far as people getting upset that this article states that BPD people CAN be manipulative, and that they don't often realize they are being manipulative, is a way to try to inform someone who doesn't know about this issue to some of the potential things to look out for. The fact that the author added that they often don't know they are being manipulative helps me let go of anger an resentment when I think about the ways I've certainly been manipulated.
