Have you ever known (of) a woman who wanted a temporary "out" of a marriage?

Have you ever known woman (friend’s wife, relative, even your own wife, maybe even you) who wanted to leave a marriage to “get something out of her system” and then came back or wanted back in? I know of two. I don’t know the complete details because they are casual friends but if I know two, statistically that means it is more common than I would have thought.
