Is a wife entitled to be arrogant towards her husband, disobey him, and be the one in charge of the household, using his financial loss as a pretext for this, while refusing to live with him in his home and instigating crises that led him to sell the house? And is it permissible for her family to justify her actions and overlook her previous comfortable life?

A wife must obey her husband in what is right. It is not permissible for her to withhold his rights or leave his home without his permission, unless there is a necessity. Her family should forbid her from doing so and order her to obey him. The husband's right over his wife is great: "The greatest of people in right over a woman is her husband." If the husband is unable to provide for his wife, she has the right to annul the marriage. However, if he provides for her in a reasonable manner and encounters some temporary difficulties, she does not have the right to annul the marriage. Your selling of the marital home after your wife has left it is permissible, and you must provide her with a suitable independent dwelling, whether it is owned by you, rented, or borrowed.
