Hello, I am new here. My wife of 25 years has been traumatized by her sister. Her sister coerced her while she was on chemotherapy to divorce me. Luckily I was able to stop it. Never a talk of divorce before her sister showed up while she was ill. Long story short, her sister is a very wealthy Sadistic Narcissist who my wife feared her whole life. Luckily I got my wife back from her grasp ten years ago. After the death of my wife's mother, the sister went to town on my wife again and Narcissisted her. My wife is from another country and this all happened why she was out of town. The kicker is my wife now associates me with her sister. In a trauma bond with her sister. Five years now. Her sister is jealous and envious of us that my wife lives here and she cannot get her hands on her. Spent 10's of thousands of dollars on best psychiatrist and therapy. She is getting better but still very hard. Has anybody experienced anything like this. So so very painful. G damn these Narcissists who cannot leave people alone.
