I think tough love is best with my elderly mother. After a health crisis, I firmly told my mother to come home with me. My narcissistic brother gave in to her desires to go to her home. His "plan" involved me and his girlfriend dividing our time in her home. He didn't even bother to consult me. I tried at first, but backed away because he was too domineering, controlling and judgmental. Now, his girlfriend is backing away also. He is taking time off from work to care for mom himself rather than admitting that he was wrong. This has been ongoing for 6 weeks. He and mom are in this co-dependent dance. He gets narcissistic supply and she gets to stay in her home even though she can't care for herself. He is currently on FMLA leave without pay. I fear that his next step will be to take control of her money....out of necessity. He is acting as gatekeeper. He recently changed her locks so I no longer have a key to her home. When I call, he often answers and won't let me talk to her. Do I have any legal remedies?
