Ex and I separated in Nov 2019.
Ex moved in with his mum.
Me and 3 children stayed in home.
Mortgage was due to be paid off 2021 so agreement at the time was ex would save to meet the endowment policy short fall rather than pay maintenance whilst I remained with kids in home.
Fast forward to now and ex paid off the mortgage last week
Now we move on to maintenance payments for 2 children.
According to gov website he should pay £385 a month.
I've said that £300 is fine as he still pays building insurance.
He's kicking off saying he can't afford this. He wants to pay £200.
Technically I don't need the money. I work but sometimes we dont have enough to cover the extras so I see this money as for the kids uniforms and holidays etc.
Things have got nasty.
I've told him I want mediation and he's refusing. I'm going to go ahead and arrange.
He's pleading poverty. He earns 27500, lives with mum and has no debt. I'm so confused as to how he can't pay maintenance. He's also saying it should be worked out after tax and insurance and rent and petrol costs!!!!!!!!!!
What do I do?
