This has to be the most ridiculous thing on this thread.
The Op is subsidising the NRP. Because Op has the kids most of the time, pays for their clothes, extras, school things, food, heating etc when they are with them. AND doesn’t claim CMS. The NRP is paying practically nothing towards their children. Apart from some food costs for 4 days out of the month.
You really believe a parent who is shouldering the vast majority of costs for the children, should have to pay the NRP, because that parent has made decisions that have lowered their own standard of living?
what if the NRP decided to give up work? What if the NRP doesn’t have as nice a house for the kids to stay in? Should the resident bare the cost of that as well?
So what if you can’t take it with you? What does that have to do with anything? Who says Op thinks they can take it with them? Of course Op can’t. But what they can do is secure their own children financial future. Secure their own. Enjoy the money they earn while they are here. Eventually, if a very high earner, make sure their grandkids have savings. Leave enough to make a huge difference in their kids and grandkids lives.
it’s not going to war with someone to refuse to further subside them, their new partner and new child. If the NRP really cared about the life they can give the kids, they wouldn’t make decisions that negatively impact their financial situation. Such as having more children. The responsibility to change the situation lays with the NRP. Not the person who is already shouldering 99% of the cost of their children already.
