Answer by Danavir Goswami
A wife should be faithful to her husband and never, even for a second, think of uniting with any other man. This holds true if the husband is poor, unclean, diseased, unfaithful, etc. The wife should not consider finding another husband unless her husband dies or takes sannyasa and the widow is young and without issue.
There are many examples of chaste wives whose husbands were poor (Damayanti and Nala), blind (Gandhari and Dhrtarastra) or demonically materialistic (Kayadu and Hiranyakasipu as well as Mandodari and Ravana). In each case, the wife stayed loyal to her husband which greatly benefited her and her family.
Wives who desire to go back to Godhead should tolerate and help their less-than-perfect husbands while fixing their hearts on the eternal perfect husband, Lord Krishna.
In Vedic culture, divorce is not permitted. A chaste woman should be satisfied in all circumstances without demanding that her husband supply her with wealth. Whatever the financial standard her husband provides, she accepts favorably. She should follow religious principles, speak pleasingly, truthfully and keep clean and pure. The most important thing is she must never consider another man.
Protection of women’s chastity produces a good generation for peace, tranquility and progress of life. Western psychologists wrongly imagine that ungratified sex energy disguises itself as various sorts of psychoses. Such psychologists are ignorant to the practice of celibacy. Such psychoses are due not to celibacy but to bad association, excessive jealousy, hatred, anger, worries, intoxication, illicit sex and depression brought about by various causes.
