My dad is 88. He is overly infatuated with a 31 year old preacher at his church. She is meeting him at various places to go eat and according to him it is serious. At times his behavior is risky with how far he will drive to go meet her. He is not wanting to use his cane anymore, which he needs. He becomes confused at times and gets angry at times too. I want him to be evaluated by his doctor, but I do not want his doctor to tell him that I am requesting this. How does this work?
