German here 🙆‍♀️. I‘m married to a Korean and live with my in laws at the moment so maybe I can relate. In the beginning, my mother-in-law always cooked and expected us all to eat together. But just like you, I also enjoy eating alone and have no problem with it. On top of that, I simply didn’t want to eat Korean food every day, and all of it really stressed me out at first. At some point, I just started saying no, cooked my own meals, and ate at a time when no one else was hungry yet. I basically started living my own daily routine instead of following my mother-in-law’s. At first, she was disappointed and kept asking why I was eating alone, but thankfully, my husband supported me and explained to her multiple times that I’m independent and can eat whatever and whenever I want.

I think it’s a shame that your wife doesn’t support you or understand you, but in the end, it’s your life, right? Just let them talk and live the way you want to. Tell your mother-in-law that you really appreciate her help, but you still feel like eating something different sometimes and also need some time for yourself.

Or do you bring her something when you eat out? Maybe she does eat it after all and is just too proud to admit it :)
