Is it permissible for the husband's family to be angry with him for visiting his wife's family before his wife visits them?

The husband's visit to his wife's family is a customary act that her family should neither prevent nor be upset by, even if the wife does not visit them. The wife is not obligated to visit her husband's family, but it is part of good marital relations for each spouse to treat the other's family well, and to help them honor their parents and maintain ties of kinship, and to overlook their shortcomings; for in this lies the bringing of affection and harmony.
