Hi, I came across your post via google search because I am in a very similar position. My brother is married to a woman with NPD for the last 5 years and has 2 children with her. He seems brainwashed, like a cult member, everything she says or does is treated as sacred and perfect. Yet he is very aggressive and seething with frustration and hate most of the time. I've reached the point where I don't want to know him any more. She has him working 24/7 , he's been isolated from most of his family and friends, and she, the NPD, uses and exploits my parents for childcare, whilst being abusive to them. Basically, my mother helps for the sake of my brother but she is completely unappreciated and has to put up with insults and lies about her family, including her nephews, nieces, grandchildren etc. - it is horrible. She has accused members of my family of being jealous, and seems to have a general (and I find this depressing) disregard for people in general. Wherever she lives, the people are "scum" or they are "idiots". There is a lot more and it gets worse but I'm rambling. I just wondered what advice you got or how you coped,because tbh, I'm desperate.
