This is about my husband. He is a lecturer, and lately, something has been bothering me deeply in our marriage. In the bedroom, whenever we want to be intimate as husband and wife, he insists on a particular fantasy to get himself in the mood. He makes me dress up as a student and say this particular word, "Hello Professor, I will do anything for an A". At first, I tried to ignore the feeling and told myself it was just imagination or harmless role-play. But as time went on, I started feeling very uncomfortable. I could not stop asking myself where this idea was coming from and why it meant so much to him. As a wife, it makes me wonder if this fantasy is connected to his real life at work. I have tried to investigate quietly. I have checked his phone, observed his behavior, and paid attention to how he talks about his job and his students. So far, I have not found any concrete proof of wrongdoing. Still, the thoughts refuse to leave my mind. I love my husband, but this situation has planted fear and suspicion in my heart. I do not know if I am overthinking or if my concerns are valid. Please, do you think this is just harmless imagination, or could he be sleeping with his female students?
