The problem is my son-in-law - your diagnosis was that he has NPD and my daughter is dependent on him. They have three children who we try to keep in touch with, but it is very difficult. I am blamed for everything - he calls me a 'fruit-loop' and I am the one who has mental problems.
We visited them at Christmas and things did not go well - I found out that he is assaulting the eldest boy (putting his hands around his neck) but they had already banned us from the house (reason - I had Bronchitis!) so we were powerless to do anything for our grandson, though I told my son-in-law that we were aware what had happened and that I would dob him in to the authorities. The youngest (granddaughter) told us, very innocently, what had happened. My daughter does not realise that he is the problem and I am blamed for everything and she thinks I need to be assessed for my mental health problems.
She doesn't explain this - she just says "Mum needs to get help for her mental health".
I think he (son-in-law) suggests this and has done for many years, so she thinks the same way.
Are you a psychiatrist or a psychologist? Could I speak to one please if you do not have these qualifications. Thank you.
