Should one divorce the wife (fiancée) who does not respond to her husband and completely follows her mother's orders, or should one be patient with her and change the approach of dealing with her after marriage?

You should know that your fiancée is still under the responsibility of her family, and you have no authority over her. It is also natural that her attachment to her mother will change after marriage. We advise you to win your fiancée's mother's heart with gifts and kind words, and to expedite the marriage. You should not take your fiancée's statement "she loves you" seriously, for her mother has no influence over her to make her hate you, and there is no sane mother who does not want happiness for her daughter. We do not advise you to divorce because it is not a solution to your problem. Rather, be patient and bring her into your home.
