I'm going to try to define what I'm seeking again because I am sincerely eager for a response from someone who either suffers BPD or loves someone who does. I was married years ago to a man that was diagnosed with it and it manifested itself in periodic violence. I left the marriage, but never actually saw the ups and downs and complete closure that I have just witnessed with my boyfriend.

The change was so extreme and so sudden that it really chilled me. One of my friends told me that her exhusband has BPD and would periodically 'disappear' with no consideration of her feelings or how it might affect her. Other times, he was a kind man. I wanted to hear from someone who has actually done this to understand what happens?

Please help.
