It is not a common practice or desirable culture for a Hindu son in India to get separated from the parents upon getting married at the instance of the wife, especially when the son is the only earning member in the family. A son, brought up and given education by his parents, has a moral and legal obligation to take care and maintain the parents, when they become old and when they have either no income or have a meagre income. In India, generally people do not subscribe to the western thought, where, upon getting married or attaining majority, the son gets separated from the family. In normal circumstances, a wife is expected to be with the family of the husband after the marriage. She becomes integral to and forms part of the family of the husband and normally without any justifiable strong reason, she would never insist that her husband should get separated from the family and live only with her.
In a Hindu society, it is a pious obligation of the son to maintain the parents. If a wife makes an attempt to deviate from the normal practice and normal custom of the society, she must have some justifiable reason for that. In our opinion, normally, no husband would tolerate this and no son would like to be separated from his old parents and other family members, who are also dependent upon his income.
