Decades ago my grandfather was over 14 years older than his bride. She was 18 and he was 32. I don’t know when they began walking out or courting. My great grandfather was 20 years older than his bride. A grown man casting his eye over available young women is not unusual.
Women and men used to be more mature and back in the old days a man did not marry unless he was able to support a wife - that usually placed him in his 30s.
One of my high-school classmates married one of our former teachers. She had just turned 18. He was 39. Three decades and three kids later they’re still together.
