Partners money contributions

[Wildflower219]

So currently I am on mat leave and I am due to return to work next month. I am having to return early due to financial reasons so my work pay will be the same as I was receiving on mat leave approx 1550. My partner and I have a baby and he gives me 400 a month but that's for everything rent food bills clothes nursery fees etc. So the way I see it is that:
Partner earns approx 1100 - pays 100 for child for other relationship and gives me 400 so has 600 left for himself.
I earn 1550 - rent and council tax - 780
Bills gas electric Internet TV licence water etc - approx 180
Childs nursery 170
Food - approx 300 a month as he only likes bottled water fizzy drinks our cat food alone is 60 a month.
And on top of that I am the only one to buy baby clothes out of my own money.
AIBU to ask him to pay more especially with him now starting nursery should he pay towards this? Out total outgoings is say 1500 a month to which he pays 400 towards this. Yes I earn 450 a month more but even if I pay that on top so I pay 850 and he pays 400 I'm still paying 250 more and clothing the baby separately to all this and I buy everything for the house I have bought him all his Christmas presents my money paid for nursery decorations etc.

Well if I was Op my priority would be to ensure he pays his fair share of his living costs so I am not subsidising him. If that leaves him cashless maybe it will motivate him to work harder but Op isn’t responsible for that. And she certainly shouldn’t encourage him to pay more to his ex while she is paying his living costs![/quote]
So he should pay his way with his new girlfriend and provide for his second child but his first child can go to hell? Please explain that worldview.

This thread is so depressing.

This thread is so depressing.

My worldview is very simple. He is an adult human male. Op is not responsible for and has no control over his choices or decisions regarding his first child. He and his ex can sort out their own arrangements. However she does have a choice about whether she subsidises the roof over his head and the food he eats. Right now that is what she is doing. Putting a stop to that should be her priority.

Otherwise it is Op would would be paying extra for his first child while he fritters away £600 a month on himself....
