I have only recently learned about the sociopathic disorder. I was in a relationship with one too. I stopped all contact with him and he went everywhere scandalizing and tarnishing my name. He would talk to my friends about our sex ( needless to say, I dropped those friends too) These people are so so ruthless and hard to detect! I realized that all my exes were sociopaths too! So were my parents and siblings. It was why my life was so painful and ping-ponging all over.

Now that I am sociopath free ( I detached physically from all of them) I realize that having narcissistic sociopathic parents as a child, led me to relationships with sociopaths. I am trying to use guided meditations to get out of this mental funk. I feel so much better and optimistic about me and about life. Detaching physically and mentally works for these people.

My best advice is to get legal advice, surely someone cannot get away by just suing you all the time. It seems to be his last hold on you. If you can stop him from the suing you, you will be at peace again. Involve the cops, sociopaths apparently are very fragile scared people. Rebuff him through the system, I am sure it can be done. When he sees an authority coming at him, he will long gone.
