So, my ex pays a measly £6.31 a week child maintenance for my two children which I have full time. she owes me arrears of thousands, but, because she is on benefits I will never see any more money from her. this infuriating fact is most annoying. Now turns out she has had another child. Why can people who are unwilling/able to pay for two children they already have but don't see have another child ? surely if you can't pay for two already you can't afford another child ?! it grinds my gears that she is getting away with this whilst I struggle.
