I'm disgusted by this thread. Progressive society !!!!
The problem here is we don't as a society vilify absentee non contributing parents - we instead victim blame the insitu parent doing their hardest to make ends meet and raise our future generations.
We need to give ourselves a proper head wobble.
Your Ex is scum. Infact, scum squared as he does this not just to your children but his other child. Yet he walks free in society - we have all got this so wrong.
Childcare is one of the biggest barriers to gaining control of finances and being free to progress your own life and control.
If we could find a way of pulling together and acknowledging this we might actually be able to instigate change for future victims and break down some of the single parent stigma.
The CMS encourage trying an informal agreement yourself. Shockingly it can work to do an estimate based on things you know, put it in writing and see what happens. Obviously, it can not work but its worth trying. Then theres the never quite having the confidence to build that money into your budget as game playing can commence.
I've tried to live debt free. I don't actually think this was always the wisest thing to do. When you did your studies and took on your student loans you did it investing in your future. Knowing your potential could be reached and you'd be able to repay that debt.
Now is time to reinvest in your future and your career progression. Your childcare costs are going to be significantly higher for the first few years than subsequent ones and with young DC career progression can also be a little more challenging - as they become more independent (it flys by) your career can potentially progress again.
Interest rates are at an all time low. If you spread the costs over say 10 years rather than paying all upfront you may give yourself a little breathing space and make the journey forwards more comfortable for you all.
You're obviously an intelligent women. It feels like a minefield at first. You will survive. You will find your path forwards and if you have days where you can skim over the negative posters mumsnet can see you through, just like it did me and many, many others here.
