I have also read your other recent posts, and can totally relate to the frustration and anger and need to expose your ex to the world for what he is. How I have been there too... How many sleepless nights I have had simply burning up with rage and wanting to KILL him. I bailed him out financially a year ago from my inheritance I got when my mother died when he had lost his job. He still owes me a significant amount of money - however, my paying off his bank loan did not give rise to any guilt on his part to want to end his relationship. He was always so slick at keeping his life in different compartments and I really don't think he let feelings or emotions cross over to any of them - he simply assumed a different stance/persona when appropriate.
The advice from everyone on this forum is right - go no contact. The most effective behaviour towards your ex is to be indifferent and show no concern. If he is like my husband, he could never stand it when he got ignored - let alone dumped.
HPDs are charmers, they excel at getting people on-side. Their primary concern is their own happiness and well being, and they will do what it takes to ensure that they have endless supplies of admiration and positive reinforcement. If it were not for a casual remark made by an old (male) acquaintance of my husband about him potentially having a personality disorder, and something my sister said about his narcissism, I would never have realised what his issues were, and would probably still be devaluing myself as not good enough and that's why he started yet another affair.
My HPD husband is the most selfish person - he always engineers things to suit himself. He cannot deal with the mundane or the monotonous. When things get too boring for him he creates a drama. He has no introspection and can only see things in black or white terms. I cannot count the number of times when he was late (in fact he was NEVER punctual), used to go for 'a quick drink after work' and then get home in the very small hours of the morning without so much as a telephone call to let us know he was ok, and the LIES LIES LIES and more LIES and #######4 he told everyone. He also had a large number of women 'friends' he kept and regularly met them for drinks, lunch etc. Some of these women friends were actually ex-lovers, although why they wanted to remain friends with him is a source of much puzzlement to me....
Understanding the disorder is a huge step to realising why, what we victims need to do now is to use this knowledge and make sure we don't make the same mistakes again (note I am assuming that there will be a healthy relationship for me in the future

Someone on this forum said that to deal with an HPD effectively is to only react to what they do and not to what they say - how very very true that piece of advice is.
