Genuine question - why are you putting up with his not only never cooking but not pulling his weight otherwise apparently?
That sounds very much like he’s lazy rather than lacks confidence/skill.
And let’s face it there’s little skill required in putting a pizza or breaded something & chips in the oven and heating beans in a pan/microwave! Even pesto pasta isn’t that hard.
Yes there are very rarely people who genuinely can’t cook I know a couple, one is banned from using her cooker as she’s a fire hazard! But it IS rare.
It’s far more often a case of “won’t” rather than “can’t”
My dad is pretty sexist and was very much of the “wife work” attitude but even he can do (or could before he got too sick to stand) freezer to oven, a fry up, basic soup or an omelette. He used to make lovely poached eggs.
My ex “couldn’t” cook when I first met him, his mum had spoiled him and he’d gone straight from home to barracks where it was much cheaper and easier to use the mess and there were little in the way of food storage and kitchen equipment or space to store in the barrack block.
I was a lodger in a house and when he came to mine I expected him at the very least to help by peeling/chopping veggies and doing the dishes after (properly! Not just the plates and cutlery but the pans too and wiping down the counters etc)
Over the years I gradually taught him to cook, started with basic easy stuff and worked up from there. By the time we split he was perfectly capable of doing and planning at least a weeks worth of meals.
I also taught him about nutrients and their benefits and thus why it’s not healthy to eat a limited range/eat the same thing constantly - he was also extremely fussy when I met him there were literally 6 foods he would eat and 2 of them were bread and potatoes! Again down to his mother (she’s otherwise a lovely lady but she spoiled all her dc far too much on food side and they all ended up ridiculously fussy to the point they weren’t healthy in 2 cases)
@RobertSmithdoesmyhair how exactly is he “wonderful” if he’s of no practical use?!
Those posters where the non cooking partner makes up for it elsewhere - absolutely fine as long as the division of labour is genuinely fair and both parties happy.
But where the non cooking party is simply lazy and selfish that’s not on.
