He should support the children NOT the mother.
She deserves nothing.
What a stupid post. Personally, we have household income, made up of my wages, DH's income, tax credits, child benefit etc. I manage that income and budget as I see fit, to make sure our bills are paid, food on the tabel, etc. If DH and I split I would still expect his contribution, although it would be less than now of course since his living costs would be removed from the equation. I would still expect to manage the household income as I see fit, as the person who manages the home where my DS lives.
I would not expect DH to buy DS's clothes, for example, or buy his nappies, or as he gets older to pay for his swimming club, or whatever. I would expect to be given cash and left to spend it as I see fit and necessary.
DS will always have a bedroom and use hot water and electricity etc. The money that DH would pay me would go towards those costs. So the money would go to me. It would not be about 'deserving' money but about DS having a decent standard of living.
Although as i am the main earner it's all academic. I certainly didn't get impregnated by DH for his money.
