has his emotional connection finally been severed from me?

I was recently the subject of a HPD that swing over also to NPD romantic emotional attachment, and have known for sometime that they had this illness. They never knew that I knew and I always kept them at arms length because i had already been taking in at the very start when I was idealised. (I have a psychologist friend who warned me this person was most probably HPD and when i abandoned them they swung over to NPD). They kept trying to reattach to me for about 18 months after the honeymoon period and I always remained civiil, but emotionally unnattached.

MY question is this. They have found a new gf now, and have already idealised her, and are feeling that the intimacy is more than it actually is. Their words "I have found my soul mate" after talking seriously for 3.5 weeks. This person is still disordered, i know that for sure. I read in the HPD forum though a comment by a male sufferer that if they come across ex's they relink.

Can I get some more feedbavck on this. I want to know if i am finally off the hook with this person, or will they relink with me because im an ex and or because I am good narcissistic supply. I am attractive, single, connected and run online ministry (and this person considered me a good food supply and continually tried to recycle it).

I know from an NPD persepctive I could be recycled in future, but I would like to hear it from the perspective of HPD's sufferes, particularly male if that is possible.

Thanks

I don´t have HPD or NPD but I would like to write few things. Maybe it could help you.
In my opinion "recycling a ex" is common if someone has a HPD to get attention, NPD to get narcissistic supply, BPD to not be alone and show as a victim to get a parental relationship.

Maybe you could be friendly but keep distance. So hopefully he could notice that you are no longer "the source of supply". Try to avoid any contact no matter what he say and try to be unemotional.

Maybe he try it again but be careful and don´t trap into the manipulation.

thank you for replying very helpful
