The Idea of Marriage
The idea behind the institution of marriage in Hinduism is to foster, not self-interest, but love for the entire family. Practice of self-restraint is the ideal of marriage in Hinduism. It is the love and duty cultivated for the entire family that prevents the break-ups.
Men by nature are less capable of self-restraint than women. That is why, after marriage the Hindu women lead the men by keeping the lustful propensities under control. While married, thought of any other man does not enter the mind of a Hindu lady until she loses her faith in her husband due to his consistent misbehavior and 'don't care' attitude.
