Found a great book to read which although not about HPD specifically will resonate with lots of people here who are still obsessing about our "lost loves"

...although the contents may not apply to everyone here, it does explain in laymans terrms how many of us are sucked in to dysfunctional relationships with "damaged partners" because of our own "dysfunctional" upbringing...(even if you didn't think you had one...read this, you may be surprised to find that you were indeed damaged by an unthinking parent)....The book is
"Obsessive Love" by Dr Susan Forward...it is truly a great read and a real eye-opener, even if you thought you knew this stuff about needing to re-create old dramas....also a large section at the back about how to rid ourselves of our obsessions and our unhealthy choices...I cant recommend it enough
