Is it permissible to continue shunning an unbearable wife, while she remains in the same house but with a separate entrance, in order to preserve the children and out of consideration for her family's difficult circumstances, instead of divorcing?

If a wife is verbally abusive towards her husband and raises her voice at him, she is considered disobedient (nashiz), but this disobedience alone does not nullify her right to overnight lodging. Allah Almighty has clarified how to deal with a disobedient wife. The maximum period of desertion (hajr) according to scholars is one month, and it should be in the marital bed. If the wife does not desist from her disobedience, then divorcing her is recommended, as it has been reported that the Prophet (peace be upon him) said: "There are three whose supplications are not answered: a man who had a bad-tempered wife but did not divorce her..." (the rest of the Hadith).
