> It isn't. Pardon me, but what isn’t? Are you saying it is not popular? > I don't know of a single couple in my personal life or extended group of friends that went poly and remained a couple past 5 years. This sentence makes it sound like you know multiple people who went poly. Which is exactly what “become so popular” mean. Then it sounds like you argue that it doesn’t make sense and the affected mariages didn’t last. Which is fine I guess, but that is a different question from if it is popular or not. > Why get married if you're going to be polyamorous. I don’t understand this question either. Many people are polyamorous without getting married. Perfectly valid choice. Then some people are first married, they live in a monogamous marriage and then they realise that the lifestyle is not working out for them. The choice for these people is not between monogamous marriage and polyamory but between divorce and polyamory. The question you are asking presuposes that people are aware that they want a polyamorous relationship at the time when they get married. Then of course there can be people who want a marriage for some legal or social protection. Let those things be preceived or real. If we believe that two adults can promise each other to stick together and help each other in good and bad, sickness and health, why couldn’t the same thing work just because they also have other people in their lives?
