What is the religious ruling regarding a husband's statement to his wife, "I will have no dignity if I don't divorce you," after she insulted him by saying, "You have no dignity"?

If the husband, by saying "I have no dignity except by divorcing you," means that he will not feel his dignity except if he divorces her, but he does not divorce her, then divorce is not binding on him. And a wife's cursing her husband is forbidden, and what is obligatory upon her is to honor and revere him and fulfill his rights.
