I don't think so. IMHO, the real issue is: "who gets to define what marriage is and isn't?" Or, "who makes the rules?" Partnership, sacrifice, common good, open communication, shared values and shared responsibilities and all that sound really good, but they're all general terms - and in the real world it's the details that matter. And what works for one situation doesn't necessarily work for another. Having one's own time/space/money can often be the key to having a relationship survive and prosper. What makes it more of a sporting course is that "what works" changes over time. Some of what we know from the past is useful, some isn't, and the mix is always changing.
