I'm pretty sure my wife has it too. She had a trying childhood and parents divorced. The counselors we have seen are happy to take our money and not look beyond false front she presents to them. They are also keen on validating my feelings instead of believing me that there is something wrong with her. She also cut off ties with family when they did something innocent. She calls her in-laws toxic, and tells our children that.
I'm wondering what to do as well, and I don't feel at all hopeful for the future. I wonder if I divorce if my children will develop her same problem.
