How to deal with a spouse who has moral or psychological defects and is not willing or able to reform?

Question: My question does not concern me. It is about how to deal with a husband or a wife who has qualities of nervousness, stupidity, ignorance, indifference, obscenity, or haughtiness but insists on adhering to these qualities and does not accept advices or think of reform.

The answer: I advise the people, who are afflicted with such spouses, to regard what they consider to be important things in the light of their benefits. Sometimes patience and silence are preferred because they are the best ways to defeat the problems that lie in the way of success as mentioned in one of the traditions “He is happy whose tongue is silent and whose speech is little but meaningful”, whereas at other times divorce and separation must be preferred.
