He has been banned from the transit bus because they have a video of her touching my dad on 2 separate occasions and he is suspended from the senior center for inappropriate sexual behavior with her. He doesn't remember any of this. He is so sad. He feels everyone is against him and this woman is trying to isolate him from his family. Dad's dementia is rapidly getting worse because of the turmoil with this woman but we cannot get her to stay away. When she isn't there he says he doesn't know her and doesn't want her around but she is telling everyone they are getting married. My dad's mind is a mess. He is a pillar of the community and in this county. What do I do?
