I feel that husbands should not be entitiled for maintenance from their wives.
Following tradition, husbands should provide for their wives and children. If a man cannot provide for his wife, how can he think of marrying her? Just for the sake of his own comfort. If so, then he should be ready for adjustment with his wife, and no cause of dispute should occur.
In case such a marriage does happen, where man subsides on wives income, it should remain the wives' wish whether she would provide maintenace for her husband. The husband should be entitled to wife's maintenance, only if the husband is left with no means to support himseleves, or when the difference in their income is very vast.
Failing this, the rule would become a means of abuse against wife, just like other practices that are prevalent, like dowry.
