Before I get started- I know that 'family money' is a big thing on MN. But for various reasons it is not something we do. DH pays mortgage and bills, I pay everything else; childcare, groceries, clothes holidays etc. It works out roughly equal.
Before we got married and had kids we had a discussion about money and came to this agreement based on DH's tight fistedness. The theory being, if we had to go halves on holidays, clothes, Xmas etc they would all be shit because DH hates to spend money. He agreed to this 100%.
The only deviation from this is that DH agreed to pay for his kids' expenses when they come EOW. He has 3 kids now aged 13-16. We have a baby and a toddler together.
Without fail, EOW, DH 'forgets' to stock up on groceries for his kids. And 3 kids of that age eat A LOT. So, every other Monday the cupboards and fridge are empty. I replenish at a cost of average £70.
I love these kids and wouldn't want them to go without obviously, but why should it cost me £140 a month??
DH is well off but has a strange attitude to spending money on other people. ( hence our pre marriage and kids agreement!)
Despite being able to afford more, he only pays minimum child support to his ex. (She is very wealthy and DH says she doesn't need the money. I don't think think that's the point but that's another thread... )
Anyway, I'm waffling. AIBU to get my DH to reimburse me each week for the money I have to spend on groceries for the SDC? He seems to think I'm being mean. But a) we had an agreement and b) it feels like yet another way for home to get out of paying anything for his kids!
