My bet is mom and dad got fed up supporting him and cut off the money supply. This was his response. Just conjecture.
True story. My mom worked as a nurse in a local hospital. Her immediate supervisor was a "gay" man who was an absolute shrew of a d*ck. He had sued his parents for the cost of his medical schooling. Later, he decided he was a "woman" and began "transitioning."
This demon was a large cause of my mother retiring early.
