My mother has ruined out lives. My husband and I moved my mother from the nursing home to our house out of guilt and no we are regretting it.
I have my narcissist mother living in my home and would gladly give up my inheritance for someone to take her off my hands. If anyone has the chance to have someone else take care of them, I think you should let them, and run as fast as you can because it is hell. If it depends on the nursing home getting your inheritance, then let them have it. There are some ways around that tho. But I had to feel guilty and take this mean woman that is my mom out of the nursing home and she is in her mind, bearly, but enought to say "I am not going back" and that is all it takes and you are stuck.
