Edith Wharton said this quote
“ Do you know, I began to see what marriage is for. It’s to keep people away from each other. Sometimes I think that two people who love each other can be saved from madness only by the things that come between them—children, duties, visits, bores, relations—the things that protect married people from each other. We’ve been too close together—that has been our sin. We’ve seen the nakedness of each other’s souls. ”
