Age-gap relationships — romantic partnerships in which there is a significant age difference — are of enduring interest. They’re also often framed as a question of morality.
Society has strong feelings about things like the potential for power imbalances or evolutionary instincts, for example.
When I was 27, I dated a man who was nearly my father’s age. This didn’t reflect an established age preference pattern for either one of us, and I pursued him. We were together for eight months, but it didn’t end well. Was our 20-year age gap the problem? Not entirely, but it certainly didn’t help.
