Tip: no matter what happened, it's your fault. In this regard, Skyrim mimics real life. Your wife stopped cooking, and it was something you did.
Did she say 'do these pantaloons make my butt look fat?' or "That Meela Oakenhearth says she makes better mammoth cheese than I do. What do you think?" to you recently?
No, I didn't. I just ate them. This is my second playthrough and I never had this problem with Farkas. But I don't remember eating any of the ones he gave me.
It's Vilkas or Farkas? lol, first you said Vilkas...anyway, sorry, I knew there was a bug where if you sold them the meal back, they would stop cooking(never had it though, but I only had 1 husband).
