My Cousin got married last year. My uncle, aunt, my cousin sister, my cousin brother, and his wife all live together in one house. After my cousin got married to his wife within six months she started behaving aggressively. She is violent and whenever she wants everyone to listen to her she use violence on the whole family. My Cousin has after trying everything has finally decided to divorce her but the moment he talked about divorce she became very aggressive and cut her own hand and best herself and said that she will file a domestic violence case against the whole family if he will divorce her. She keeps threatening everyone all the time and also beat them .
What can my cousin brother do in such a situation? He is totally hopeless. My aunt keep getting sick because of all this.
Can the law help them in any way?
