You are misinformed regarding the divorce issue. In the case of divorce the husband and wife must come to a mutual understanding whether they want to separate. If they decide they want to separate they will live apart for 3 months, during that three months if they decide their decision was wrong then they will get back together. If after 3 months they decide they want to divorce, then divorce is successful. Also, husband must honour the decision of the wife respectfully let go of her respectfully.
