Mom is in memory care ALF. I became her legal guardian when my brother began talking about honoring her wishes to always live at home. The problem is that he is a narcissistic manipulator who has exploited her for years to support him. Being around him is like "walking on eggshells." (Mom's words in the past-which anyone who knows him would agree). We have been trying to sell some of moms properties to pay for her care and brother refused so we had to spend $$$$ in legal fees to proceed with sales. Now we believe brother goes and says things to mom like he is the only one who cares about her and he wants to take her home and take care of her and honor his wishes, etc. we think this is contributing to some of her agitation and are now starting to track this. Has anyone else dealt with siblings with personality disorders or unacknowledged mental illness?
