A critique of feminism is that it seeks rights for women but removes any responsibilities. I'm not interested in debating feminism but it got me thinking about responsibilities in a relationship.

What are the responsibilities that go along with the title "wife"? Are they different in an LTR? Does it change if you are cohabitating or not? Or, if you are a person who thinks marriage is a broken institution, what should be the responsibilities of the wife? Are there commonalities across relationships or does the vary from person to person? What are the rights or benefits received for following through on these wifely duties?
