Agree with all OPs who say do it. With your extra earnings you can afford to pay for a cleaner, your DP will need to do his share & you can batch cook at weekends. I wouldn't be over-stressed about 'proper' meals - there's nothing wrong with beans on toast with grated cheese or baked potato with beans & cheese.
When I had little ones DH had his own businesses, I worked 3 days a week & 3 children born within 5 years of each other, we used to live out of the freezer. Every weekend I'd make either a batch of bolognaise sauce, or 5 cottage pies, a vat of curry, 5 tuna/pasta bakes and so on so that for 3 or 4 evenings in the week we would live out of the freezer & the other 2 we would have baked potatoes with baked beans, tuna mayo, egg mayo, scone-based pizza or similar. Sometimes we'd have beans on toast with grated cheese on top - nothing wrong with that.
On summer weekends I'd be having to help DH in his (catering) business as he was particularly busy then. MIL or my parents would have the children & when I picked them up I'd make a pile of sandwiches & we'd have a picnic in the garden, or if raining in front of the TV.
I had food on 2 weekly cycles so Week A Monday would be cold chicken (left over from Sunday roast), baked potato & salad, Monday week B would be chicken curry (I'd roast 2 chickens every 4 weeks & make a vat of chicken curry to freeze), Tuesday week A spag bol, Tuesday week B I'd turn the bolognaise sauce into a pasta bake, or, to ring the changes, baked potato with bolognaise sauce on it. Yes, DH would moan that he could tell it was Tuesday week B, but he could always make something different for the family if he chose & he often did.
These days I find that the prepared ravioli tortellini & similar are brilliant -I'm talking along the lines of Rana, but I buy supermarket's own brand. I freeze them, but they don't take long to cook in boiling water from frozen, in fact easy to over-cook. Stick some garlic bread in the air fryer, some tomato sauce (batch home-made with chargrilled peppers etc at weekend & frozen) in the microwave, make a salad if you've got the energy & inclination. Job done in 10 minutes. I wish they'd been available when I had young children.
