If it really isn't about the money, she can volunteer. As long as she gets no pay (including no benefits) there shouldn't be a problem. It is still strange to me. If she would do the laundry and cooking while you work, then the time you would have spent on those chores could be spent with her. You could go hiking, visit museums, play cards, take flying lessons, take scuba lessons, go dancing, etc.
