My mother has lost her ability to understand that I am her son and she thinks I am a boyfriend on some levels. She tells me that it's ok for us to be together and she has tried to touch me inappropriately and kiss me and when I rebuff her, she screams at me and "breaks up" with me. How do I handle this? She cannot grasp the concept that we are mother and son and she tells me she loves me and wants to have sex with me. I'm a mess and at a loss. Any advice?
