He can’t follow a recipe? Or is he making himself purposefully useless so you continue cooking.... it’s not that hard to read a recipe and emulate each step one by one. I did it alone as a nine year old he can do it as an adult man. Hard to tell from this alone but his response really makes it seems like he just doesn’t want to do it and he’s rather make himself a hinderance instead of being directed and follow appropriately.

Cooking for a family for almost every meal can be so exhausting NTA if you’re rather absolve yourself of the responsibility and let him do his own thing. Although I’d suggest having a conversation about how much time it’s taking, the labor, etc., to see if there’s anyway he’d start ACTUALLY pitching in instead of jumping straight to separate food/bills.
