From what I currently know I think you're being unreasonable to suggest
that lowering the amount your husband gives his ex wife would be fair,
because it wouldn't be.
Your husbands childrens mother has all sorts of bills to pay regarding her
children and has to feed, clothe them and much more - on 6k a year, thats
£250 per child per month and if you have your own children you will know that
this sort of money is hardly enough to cover all the expenses.
Regardless of the amount of time she spends with them she still has to pay
for these expenses.
Meanwhile you and your husband have slightly under 60 grand a year split between
the two of you to pay 'the bills' as in, for the house and you'll have leftovers. If his income
deducts most of his income after he has payed towards his children, then you cannot
expect him to pay for you as he has himself to pay for. If you & your husband earn
the same surely you can afford to buy things for yourself.
You and your husband could pay 25% each towards the children while you
have them? You don't have to pay towards the children however it would
be an act of kindness since your husband seems to be running out of money
I don't know how. And since you both earn slightly under £30,000 a year
and jointly pay the bills, I don't understand how your husband doesn't have money left
over to pay for his teenagers and needs to ask you for money ontop of that. You seem
to be doing fine with money and can somehow afford to pay for his children yet
he can't even though he earns the same? What's he spending his money on?
You and your husband should set up budgets.
I hate that word because of what it means but it honestly seems as though you
two need one.
working 20 hours a week means she works part time and it wouldn't give her much
money on-top of what your husband currently gives her per month.
I doubt she's earning much or your husband wouldn't have wanted to pay £500pm.
Your husbands ex wife's partner might be like you and not want to pay towards
the support of her two teens, aka your step children, so your husbands ex wife
is probably living off the money your husband gives her if that makes sense.
