I think you should be able to cook him a meal, and he should expect one.
I'm a sahp and even with two under two I managed a hot meal.
You need to batch cook a bit ( do a double portion of food and freeze) cook at lunch when babies are asleep or less needy. Choose five meals and master cooking them. You will have to cook good meals for the children soon anyway.
I don't think you can expect your DH to be a sahp because you earn more, he would be unhappy and do a bad job.
You should expect him to pitch in a bit! You need to allocate him jobs. My DH was little help when mine were tiny, he's better now after a
Lot of small steps. He's not great by any stretch but He does work really hard, long days so that our children can have a better quality of life. ( i can live with doing more domestic stuff than him) I'm just doing some freelance stuff now when they are at school.
A marriage and family is a team Effort, you may have to let some thing's slide for everyone to be happy, he won't be perfect but neither are you.
Honestly I think your not managing because your unhappy, why do you not like being at home? Not sure how you ended up without a nursery if you know you don't like being at home. Either go back to work or embrace your role.
