If it's my turn to cook, then I either ensure that I have the ingredients in advance or look in the cupboard/fridge/freezer and cook something based on what is there. I just get on with it despite working 35 hours a week and juggling the activities of two very busy kids, I don't have any family help. I have a meal ready for DH's return from work at 7. All of his meals just appear in front of him. He doesn't have any input, I do it all as he is at work.
AIBU to want him, on the one day a week when he rather grudgingly cooks, to just cook? I have to tell him what to cook, check we have everything, explain multiple times how to cook really simple things, then answer constant questions about what to do even with a written recipe in front of him. What pan should he use? How long should he cook it? Where is this? Can I just help find that? Any relaxation is out the window as I have to put down my book or stop my film to sort him out again. I try to suggest really simple things to cook or even just tell him to buy Lidl lasagne or similar but still we have to play twenty questions. His job requires him to examine a problem then find a solution then prepare a plan and he seems to manage that.
Just once it would be so nice to have a meal that requires no mental energy, no thought, no effort at all, just like he has six nights a week.
