Partner

We were talking earlier in what ifs and wouldn't it be nices, in that sort of way, and I asked if when people decide to get married or live together, if one of the things they consider is what their partner, whether wife or husband or boyfriend or girlfriend or whatever, brings to that union in terms of something practical. Our ridiculous example was, of course, work and money. As in, if I didn't feel like working for, say, a week, would my partner say to me, "Of course! Take time off and I'll get paid. Don't worry about it." Is that part of it, or were we just talking crazy?
