Marital problems

Is it permissible for a momen (believer) woman who has young children to stay in the same house but different room with a husband who is acting hypocritically (Allah knows he wants to irritate his wife by refusing to pray and use of improper words, swearing etc. because he doesn't like his wife or he is really what he shows), or she should divorce, as she doesn't want to be divorced unless living with that kind of husband is Haram. If divorce is not mandatory she is ready to have saber until she is alive because Allah's satisfaction is more impotent then everything else to her.
