Interesting conundrum! My aunt married my uncle when she was 46 and he was 26. She wouldn't marry him at first because of the age difference, but her sisters (my mother and aunt) told her she was crazy not to marry a good looking well to do younger man who wanted to marry her. They had a good run together, until she died at 92. He was heartbroken, but a few years later he married a woman 10 years his junior, and they're having fun together, too.
