Just that really. Married last year. Four children now aged 8, 9, 11, 13 from first marriage. Ex husband pays too little maintenance - £100 per month as is self employed.
For context, we both earn good money, although he earns very good money at 50% more than me. I was able to support the children without him before with no tax credits etc but it was a struggle as was paying out a lot of childcare and big mortgage. But I was fortunate to be able to own our own home, pay the bills etc, even though not much left over. This isn't about being 'poor' and I recognise how lucky I am to be able to rely just on my own income.
AIBU to expect him to pay any of the child related costs? What do you think is a fair way to split the bills?
At the moment I am paying for half of what 'we' cost and all of what the children cost. So I pay around two thirds of our house related outgoings e.g. mortgage etc as need a house for five. I also then pay for all childcare (at £800 a month), all their clothes uniform, their lunches, trips, birthday presents and so on. He does split big costs like holidays and meals out 50-50.
This means I am ending up watching the pennies at the end of the month whilst he has around £2500 more than me after house stuff is paid. He drives a new car whilst I drive one that is 12 years old. I was triggered to write this by him complaining about not being able to afford something very expensive (and nice but certainly not a necessary cost) whilst I am worrying this month about the bills.
But they are not his children.
And their father evades paying much for them.
And we both saved about a similar amount by him moving in, in terms of housing costs (mortgage, utilities, council tax).
Backstory - I have major money issues through paying for everything for cocklodger ex husband and have a father who didn't work, and a brother who seems to live off high earning women so am skewed (and anxious) around men and money.
