OK, here is my story. I hope this may help others and warn others.
I met someone out with work colleagues, she had just started at my work. We got on very well. I was married, unhappily at the time. Subsequently she and I talked and chatted a lot and I began a very passionate affair with her. She was amazing, listened, amazing in bed, said how we where supposed to me, I was the one etc. I felt on top of the world.
I left my wife and moved into my own place for some space. The girl basically moved in as well, wanted her own key ignored all her friends. It remained very passionate for a while then durprise surprise this started to wain.
She would flirt with other guys, still talk to her ex boyfriend on the phone. She had no friends, even though she had met lots of people all over the country - she kept in touch with no one. As said above she ignored all her new friends as well.
I found out from her she had never been faithful in any relationship and of course it was other peoples fault etc. I still didnt wise up. Things started to go wrong when we moved in together, she wanted to move countries, always striving for something "better", any hobbies she did never lasted. The blame started, she would get really angry, would never forgive anything and always throw everything in my face.
Eventually I split with her, NOTE she did not want to split with me. I knew she had kissed a guy I worked with and I had enough. Even when we split she was crying saying she wanted to stay together.
After the split we saw one another as friends and she said she wanted to get back together, when I showed an interest she said she didnt love me anymore. I felt utterly devastated and heartbroken.
After taking time to heal, I have thought a lot about her personality and what she did. She is 100% HPD in my opinion. All the traits fit. She lost her father as a child.
