Another difficulty is that in modern civilization everyone is independent spirited. The girls are no longer very much humble and submissive to their husbands. So you must be prepared to tolerate such whims of your future wife. According to our Vedic civilization, disagreements between husband and wife is not taken very seriously. But the modern age allows divorce even, either by the husband or by the wife. These things are not good. But after marrying, certainly there will be some disagreement or misunderstanding between husband and wife.
