How can one deal with the mother-in-law's long stay at home during the summer holidays, which causes psychological and physical exhaustion for the housewife, given the brother-in-law's refusal to host her, and the husband's desire to please his mother?

An independent dwelling is a right of the wife, and she has the right to object to her mother-in-law living with them for an extended period. The husband should act wisely and kindly with his mother without displeasing her. It is considered good character for the wife to treat her husband's family well and help him in his dutifulness towards his parents.
