What is the legitimate Islamic solution for a married man who lives with his married brother and their sick father, and recurring problems occur between his wife and his brother's wife, and his wife constantly asks him for divorce?

The wife has a right to an independent dwelling, and the father has a right to care and dutifulness, especially during his illness and need. Both matters must be reconciled. Among the suggested solutions is to allocate another dwelling for one of the brothers to alternate staying with the father, or to divide the house into two independent sections so that each is in one section and the father is where he pleases, without the other neglecting his duty. If no solution is available, then each of them should advise his wife to be kind in companionship and to be patient.
