Is Open Marriage the Modern Couple's Answer to Infidelity?

Alternet has an interesting story on open marriages.

So, then, is open marriage the modern couple's answer to infidelity? Is it two people's attempt to reinvest in the idea of commitment, to define it on their own terms and to try to avoid divorce? Could it be viewed as an honest attempt to make marriage work? "I think that's what people tell themselves, but it raises a red flag for me," says Robboy. "It is incredibly common and incredibly destructive for couples to experiment with open marriage in response to problems or boredom in their sex life. This is not the time to experiment with open marriage. To experiment with open marriage, you have to be in an extremely healthy relationship."
