I read this story in the '70s. I think it was in an anthology of different authors. The story was set in a future with a corrupt government that sentenced opposition to be imprisoned in suspended animation for long period of time. When the character was released he figured all friends and
family including his wife were long dead. When he returned to his house it still looked the same. It turned out his wife had become a stewardess on
interstellar space flights. Because they traveled at or near the speed of light she didn't age as fast and was still living.
