I would never tell anyone about my relationship with my mother, except for maybe a therapist, but probably not even then. I suspect however, that my mother has told at least one person, and probably only this one person.
When I was in 11th grade I took an introductory psych course, the teacher was the mother of one of my close friends. She was pretty good looking but about 10 years older than my mother. She had brunette hair, blue eyes, with a slightly busty figure and a kind of a nice ass even though it seemed she didn’t put too much work into her body. She was maybe slightly over weight and 5’4. She was very much an eccentric. Because me and her son had been friends for a long time, my mother became very close friends with her. I always thought she might have suspected something between me and my mother, when I was at her house visiting my friend she would constantly ask me if I was seeing any girls. She even tried to ‘ship’ me with a girl in my psych course but that of course failed. She had a doctorate in Psychology and specialized in Freud. She would very often mention the Oedipus complex and sometimes go on rants about it. She would talk about Freudian interpretations of Hamlet and said that every son in their sub Conscience sexually desires their mother. Her son wasn’t in the class but I believe he took her class another year and I can only imagine how awkward that must have been for him.
