Answer: Both of these women have a big desire to have power over the same man. It is known from the Torah that in the past everything was the opposite way. Before his marriage, a man would bring his bride-to-be to his parent’s house, to his mother, where she would “simmer” in his familiar environment. This way, the woman understood the personality of her future husband and received all the information about him from his mother in order to connect to him correctly.
A man does exist between two women, his mother and his wife (the upper, Bina, and the lower, Malchut). This is why a man naturally tends to treat his wife as a mother to some extent, and often times he sees his mother in his wife.
All of these really descend to our world from the spiritual world. Therefore, women should forgive their husbands for this.
