Worst nightmare.

We're all about unconditional support for unconventional sexualities here - but you'd better be monogamous! lol

Sorry that you feel that way, @lamortenmarche, but I have two things to say to you:
1. I don't really care
2. I am a girl

Personally I wouldn't allow my SO to just fuck someone else because "yay party" but if the guy is okay with it? Who the fuck are we to judge the couple? It's all about communication, if they agree that it's cool then I have nothing else to say.
Also, yes, people here upvote/downvote in a very petty way. They never explain why is it they disagree with you, which could lead to a fruitful conversation, they just downvote. And they upvote the most judgmental bullshit.

People don't understand that even though it is their body, and their choice what to do with it, when you enter a relationship or get married, these things are wrong. Maybe your partner enjoys it or is fine with it, but it is still uncommon for everyone else. Her actions are considered cheating and are morally wrong. For instance if some one said they enjoyed eating puppies, that's their opinion, but I would downvote. As would everyone else

How's the view from that high horse, o great king? Newsflash: you don't get a say in what's morally valid in my marriage or my wife's sexuality.

"As would everyone else." Yeah everyone else who is a judgmental prick, that's for sure. I repeat: your nosey self has ABSOLUTELY NO BUSINESS in other's people's bedrooms. As long as there's consent, the couple can have an orgy with other couples for all I care.
As far as that puppy eating thing is concerned? In China they eat dogs, and I don't care either. Now what I do care about is how the animal is treated and how painlessly it is killed. For instance, the Chinese believe that if you torture a dog, it will taste better. Now that is disgusting and I'm completely against that, because the animal suffers. But if they killed the dogs painlessly? I'm totally okay with that. Also, the fact that you mention eating dogs and not the fact that even in the western countries we mostly treat livestock very poorly shows that you are a massive hypocrite. "Boohoo they eat puppies but nvm let me eat that chicken that probably spent its whole life in a tiny cage and was force-fed hormones."

Publicly posting videos and talking about how you live privately then screaming, "You are not allowed to judge me!" does not take away the invitation you gave to every single person to judge you. Whether it be good or bad, accept the fact that not everyone thinks like you. But I do love the hypocrisy of getting angry about how others judge you, because your asinine feelings are somehow the only valid ones. Delicious!

We were not talking about that. You either don't know what you're talking about or are making a false equivalence on purpose, and I'm not sure which is worse. willfree suggested that if a couple has an arrangement that the partner can sleep with someone else on a certain occasion, that it's entirely their thing and nobody should be able to talk into their own private business. As long as there's consent, it's good. In the case of this post there was obviously no such arrangement, that's why the guy cancelled the wedding. But there are couples with such arrangements out there, and no nosey judgmental twat should be able to control what they do in their own bedroom.
I suggest you go back and read all the comments in this thread before commenting, it will help you avoid such an embarrassment in the future.

Welcome to Funsubstance. Fuckholery abounds by the handful, stupidity reigns unchecked, and hypocrisy is a familiar neighbor.

Which was a reference to what, exactly?

You all spout tolerance and acceptance of lifestyles (LGBT) and religion and whatnot and then you all start harping on someone for polygamy/premarital sex. Furthermore, you all assume that the couple didn't give the OK for this beforehand. Obviously from the context of the post they didn't but you all still shoot down the thought that it's possible to be polygamous without cheating.

"You all" I was JUST literally advocating that they can do whatever they want, as long as it's consensual. Please don't lump me in with these judgmental assholes.
(Here I thought that sticking your nose in other people's bedrooms was just what old redneck fundamentalists do. Apparently not.)

Willfree also was advocating people be less judgmental of others. Kingme comes almost close. In this particular case it is cheating since he called off the marriage. In a "traditional" relationship that is obviously cheating, and in an open relationship it is a simple if not MORE important to respect the agreement between you and your partner, the fact they broke up means she was cheating period. Even the original comment in this thread specifically said cheating. It did not call out non monogamy. It called out cheating- when one partner breaks the rules. A breach of trust and safety which undermines the foundation of any relationship be it open or otherwise. There's always a line in any relationship and in theirs she crossed it. Live as you like. It's not my business nor is this, but there's no need to come in here guns blazing. I'm sure there are people here who aren't open to other ways. Easy option- don't fuck any of them and everyone can get along fine.
