How can a wife deal with a husband who treats her badly and fails to fulfill his marital duties, which has led to a deterioration in her psychological state, given her desire not to break up the family?

A wife has the right to seek a divorce if she is harmed by her husband, because he is obligated to treat her kindly and fulfill her rights concerning intimacy, maintenance, and housing. This is based on the Almighty's saying: "And live with them honorably" (Quran 4:19), and the Prophet, peace and blessings be upon him, said: "Fear Allah concerning women, for they are your captives. You have taken them as a trust from Allah, and have made their private parts lawful with the word of Allah. And their rights upon you are their provision and clothing according to what is reasonable." However, it is advisable to be patient, continue offering advice, and use legitimate means to attract the husband. Relatives and friends who he listens to can advise him, or he can be referred to a psychiatrist, and specialists in family problems can be consulted.
