What about groceries or things like household maintenance? Do you share a car? And he doesn’t pay for any of your child’s needs at all? At the very least isn’t that something you should reasonably ask him to help with ?He's doesn't spend it, it's all in a business account so not a disposable income as such if that makes sence. We have one child who's 5. He pays for holdidays but I still take a big amount of spending money and pay for most things when away. We do go big holidays such as dubai etc which I know we are fortunate to do but I paid for me and daughter to go Disney land Paris and he didn't pay a penny. He doesn't contribute to her needing new clothes or shoes etc
No need to answer if you feel we are prying. But I am also curious, and hope you are ok...
