And this is why marrying someone who shares interests and hobbies with you is a good thing. Wildly different interests just leads to resentment as neither side will agree on what to do, and compromising is just going to lead to both sides feeling like half their time is being wasted. I consider myself pretty lucky that I can play Co-Op or trade "Let's Play" experiences with my spouse, rather than both of us having to do shit we don't like.
As for the story, I don't think I would have gotten myself in the same situation as the husband anyway because I acknowledge the importance of shared interests. However, on the off chance that I did wind up in his shoes, I'd probably take it very personally, and would probably threaten divorce. Whether or not I'd follow through on the threat would depend on how things go from there. A joke is one thing, but this goes well beyond being a joke to me. This has gotten national media attention, hurting both of their reputations. I don't like being put on the spot and made to look like a fool, and I especially wouldn't want it to happen with the eyes of the world watching. Beyond that, and much more importantly (since let's face it, the world's not gonna care anymore come next week), this joke shows, to me at least, a clear lack of respect for the husband. Why talk about an issue with your husband when you can instead publicly shame him, right? If that's the kind of behavior I could expect from my spouse whenever there's a hiccup in the marriage, I'd rather cut my losses early than stick with it and be miserable.
