The answer
Shepherd of Hermas says, “If a man has a wife who believes in the Lord, and if he finds her in adultery, does the man sin if he continues to live with her? If the husband knows that his wife has gone astray, and if the woman does not repent, but persists in her fornication, and yet the husband continues to live with her, he also is guilty of her crime, and an accomplice in her adultery.”1776
