He's single, lonely, love sick. F-I-L turns 90 today. Living alone, in the country. 3rd wife passed away 6 months ago. Met her through a dating service and wants to do the same all over again. That was a nightmare; no $$ left anymore. Does not want to move but needs companionship. I have POA but he does most everything with me double checking. Making poor choices, like dating service, makes mistakes in check book, sometimes. Forgetful---little things like, how to turn on phone, manage remote control, or how to run the washing machine. Not always however, random. Gets upset when there's no mail delivery, even on Sundays. Still drives locally. Has pets but they are allowed to mess in the house. Physically pretty good for 90. Very hard of hearing. Really want for him to move into assisted living with meals, housekeeping, and a possibility for a social life. Also feel that an allowance is the best idea so that no more financial mistakes are made and he can no longer order something from every piece of junk mail that arrives, including a new wife I suppose. Help.
