Thinking about the way forward here.. firstly, I don't think you're going to end up divorced over this, but in order to navigate these waters of stupidity, you need a plan.

I'd want to know from your husband, how invested in these people he is. Are these people he needs to continue to see for work? If so, a simple "I made it up. All this talk about women's looks is shallow and not good for me to indulge."

This is done without you involved, and preferably you are never have to see them or deal with that group at all. At your option he may mention you and that you were hurt by this.

If there are deeper or longer term friendships at stake, and your presence needs to be there, I would have them over individually for dinner or something. Maybe mention you had heard about what happened and were curious if you'd really judge Dick on his wife's looks alone, or if they'd consider other factors like cooking or juggling yams as well? Some kind of mild humor there. Hmm.. yeah, this ain't exactly easy. Something something, light banter, they get to know how sweet you are, learn that Dick has a solid wife, and are not in a position to deride him for his previous stupidity. The key would be just you three, not gangs of men in your home.

The best case would be where he can just cut these friends , learn his valuable life lesson, and be sure not to be that shallow ever again.

This is not a pretty situation. Maybe you should just show up dressed like a Juggalo, start smacking asses and saying "Wwwwoooooooooooooooo!". Shit I don't know. Tell your husband to find easier things to fix when he screws up next time.

Good luck!
