Origen

“ But as to whether her being caught in the act of poisoning or committing murder, furnishes any defence of his dismissal of her, you can inquire yourselves; for the husband can also in other ways than by putting her away cause his own wife to commit adultery; as, for example, allowing her to do what she wishes beyond what is fitting, and stooping to friendship with what men she wishes, for often from the simplicity of husbands such false steps happen to wives ”

“ And perhaps this man is more culpable who, so far as it rests with him, makes her an adulteress when he does not satisfy her desires than he who, for other reason than fornication, has sent her away,—for poisoning or murder or any of the most grievous sins. But as a woman is an adulteress, even though she seem to be married to a man, while the former husband is still living, so also the man who seems to marry her who has been put away, does not so much marry her as commit adultery with her according to the declaration of our Saviour. ”
