My husband is 2 years younger than I am. When we first met, he was a freshman in college and I was a junior. I thought he was very sweet, but refused to date him because of the age thing. My mother advised me to "go out with him just once and see what happens. You don't have to marry him!"

My cousin's daughter visited from Italy last year. She was 20 and her husband was 33. That seems quite acceptable there.
