Exh/ temp unemployed/ maintenance

[flatscreenlife]

My exh has been temporarily unemployed due to the pandemic. He will receive a total of £275 per week in payments plus a possible extra£100 per week .
We are not legally separated yet but work well as coparents and he pays approx£200 week maintanance for our three kids as they live with me 80% of the time.
We are meant to be in lock down but I've found out that his girlfriend travels to see him
For a few days every few days . She lives 100km away.
He would like 50/50 custody now as he is off and he would not have to pay me maintenance.

I have been clear that under no circumstances will I allow the children to spend half the time with him
When his oh is essentially there when the children are not.
I am being really anal
About this lockdown to the point of obsession as we cannot afford to get unwell from a health perspective. Our kids have not had any human contact outside of either of us in three weeks and besides the shop, neither have I.
I have asked him if he is willing to forego his girlfriends visits for lockdown in the kids best interests and then do 50/50 .
He is not willing to do that as he says she is his only comfort and support at the moment.

Ive offered for him to stop maintaenance of£50 per week for now so he would in effect be paying £150( mortgage ) as maintenance .

He won't get a job as he feels he would only be £ 50 better off per week and his redundancy may be affected if he is permanently unemployed . He has savings of approx £7k.
How would you deal with this?

He thinks I am only being 'partly ' fair as I am being paid.

Op, your posts describe a mess of a situation.

Your DH flouting the NHS / government rules around coronavirus is one topic. I don't think yabu. But Your co parenting setup re: finances is ridiculous, you haven't got reasonable expectations at all.

Why do you keep talking about him paying the mortgage? Or postponing current maintenance to pay back later? He's paying an unsustainable amount to you currently, you need to get a grip.

There's no reason to not consider 50/50 access if he will agree to keeping lockdown rules formally.

You need to legally separate, and define financial and custody arrangements properly. With a mediator if needed.

Your wierd, informal split arrangements have led you to this. Not the pandemic.

Sort it out like adults. Both of you.

You should pay half the mortgage anyway, presuming you both own the house.

He doesn't need to postpone payments, he just increases when he starts earning.

£200 p/w sounds a fair whack, so am assuming he was a high earner?
