Are these “ other things that you couldn’t afford to pay “ things that financially benefit you alone, both of you or him alone ?
Because when you spent your savings on the maternity leave , the only person who benefitted financially was him.
If you cut down your hours but pay the same, he benefits from paying less of the bills and also the bill for childcare.
You lose from less pension, less career and promotion opportunities , you pay more of the bills and your will almost certainly have to do more unpaid work at home than him, because you are PT and he is FT.
When your child is sick and can’t go to nursery, YOU will have to take the parental leave not him, because his job is a Big Man Job and your job is a Silly Mummy Pin Money Job.
You will have to do the pick ups and drop offs because ^^
Your boss will get pissed off at you taking all the extra time off when your child has two parents. you will seem as not a team player because you expect everyone else to cover for your husband and he doesn’t even work there.
Your husband will get more promotions and money and you will get less. You will do more childcare and housework and wifework and he will do less. He will get more power in the relationship and you will get less.
It’s a very bad move for you.
I suggest you see more of your baby by sharing the housework and Wife work 50:50 when you are both at home. And using joint money to buy in help to do housework etc .
Don’t drop a day with a man like the one you are married to.
