Is a husband entitled to accompany his wife to ward off corruption, especially since she goes daily with a taxi driver and there are other girls with him?

There is no objection to the husband accompanying his wife to college; indeed, he has more right to do so than a stranger. However, this should be done with the agreement of the wife's guardian, as it is customary for a husband not to accompany his wife before the wedding, and before consummation, the wife's obedience is due to her guardian. Therefore, if the wife's father refuses your accompanying her, she must obey him.
