I am a single middle-school teacher in his early 40s. Two years ago I had a sexual affair with the mother of two students who attended the school where I teach. A year ago, her husband caught us, and the affair ended. Until this year, I have never taught one of my former affair partner’s daughters, which I guess made it easier for her husband to stomach my working at his daughters’ school. Now I have the elder child in one of my classes. Because I coach the volleyball team and the younger daughter took up the sport this year, I now also have nearly daily contact with her, too. I know it was stupid and wrong to sleep with a married woman; I make no apologies for my behavior. That said, I was never in love with my affair partner, and I have no interest in rekindling our affair. She and her husband don’t believe me. If I ever compliment or speak to their daughters—I assume they find out because they interrogate the girls—one or both of them will email me to tell me to watch it. She threatens to go to my boss if I interact with her daughters too much and “expose” me. Last week I gave the elder daughter a C-minus on a poorly written essay, and they accused me of punishing her because the affair ended. I do not know how I can teach or coach my students if I cannot speak to them or give them the grades they deserve. Frankly, I’m wondering if I should talk to my boss about this and take away their power to threaten me. Another part of me wants to tell them I am not interested in the mom and just want to do my job.
