Is it permissible for a husband to boycott his wife and take her to her parents' house?

Question:
She says: I am married to a man who is also married to another woman. He constantly repeats that he married a second time to find relief, and he does not accept any mistake from me, even though I try to please him and I sometimes make mistakes. Now, he has boycotted me, placed me with my family, and refused to let me return. Is his action permissible?

Answer:
You have the choice as long as he does this. No, he must be just. If he does this, ask for a divorce. Then, he must be just, fulfill the obligatory duties, and treat you both equally. If you say, "Divorce me," he must either be just or divorce you. If he does not do so, take the matter to the court. Let him take the matter to the court. So, the husband must be just or divorce you.
