My father was very controlling of my mom and me, forbidding her to have male friends unless he knew them saying they were all perverts who would try to steal her from him or do something bad to her, and me from having female friends fearing they would cause trouble or I may impregnate one of them.
He too believed homosexuality did not exist and people just pretended to be gay to take advantage of those of the opposite gender. When my best friend from high school Sean revealed he was gay, daddy accused him of trying to get closer to my mom and ordered me to stop being friends with him. Sean then showed dad a photo of him and his partner holding hands and kissing and dad said it was all staged so he could gain his trust.
Knowing he was wrong I was mad and wanted to show him right but he put me down easily. I knew mom was furious also and begged her to divorce him, but she could not pay the costs of college and living on her own. We took comfort in one of her childhood friends, Verona, and told her of dad's behavior. She then revealed she was a lesbian, surprising mom and me, and would support us in whatever way possible. We thanked her, but warned to not reveal her orientation to my dad as it may infuriate him.
