[TOMT][MOVIE] A relatively recent film I saw.

I feel like it was a comedy made in the past 15 years or so, but I could be wrong. The only scene I remember is that there's a couple at someone else's house (I think for a book club?) and the couple they're visiting play all nice to them, but then the husband tells the main character that they're actually divorcing and just pretending to be happy. I feel like this conversation happened in a garage or den of some kind.
