My mother who has NPD and the early stages of dementia lives in my home despite the many adjustments we have made to accommodate her lifestyle, verbal outbursts and fits of rage. She routinely calls me a "bitch" and then usually quotes some bible scripture. She always tells me that "we aren't peers" "you are my daughter" this is laughable as she is living with me because of her many poor choices throughout her life. I don't believe in engaging nasty people on any level, why argue with a lunatic but this IS MY HOME. I'm stunned that she could be so arrogant while living in my home and all her furnishings and housing is bought and paid for by me. She is completely NOT reasonable, when I have asked her to consider her behavior, she just tells me "she likes her pound of flesh". There is no way I can get her out, she can't afford any housing and isn't ill enough for any other help. Any ideas on how to deal with this? I can't imagine living like this for another 20 years!
