nota you aren't getting it.
people are saying think about the children you have before having children with a new partner. if having more children will mean cutting the money you pay to your existing ones then you need to think very seriously about it. this might prevent being in a situation where you have two families and are having to decide which family gets your money.
also. as i said earlier, i think there should be a national minimum rate worked out by the govt. not to cover clubs and piano lessons but to cover food, shelter, clothing, heat etc. if the parents earn more then they pay more but the national minimum should cover the basics. clubs and classes outside of school should be agreed between the two parents and if one doesn't agree then the other pays as they are the one wanting them to go.
"As for think carefully before having DC's with a man who already supports his DC's from a previous relationship I would pick a man who pays for his DC's, rather than a deadbeat who doesn't, as the better father of my own child. Why wouldn't you? "
yes of course, common sense, but accept that this means he has priorities above you and that if you chose to have children with him, he will always have the same financial commitments to his first family, so dont be complaining when you have 3 children with him and money is tight. you knew the score at the start. again, common sense i would have thought.
