I really feel sorry for your children and I really hope they can get some good therapy. You and your ex both have toxic personality disorders so it will be difficult for them to find a sense of stability. My father is a narcissist but I had comfort and stability from my mother. To this day he will tell you he never did anything wrong in his life. IMO if what you were saying was true then your daughter couldn’t get enough of being with you. I truly hope you can really start to look in the mirror and start to answer some really tough questions and get some help.
