And it makes me so sad & anxious 
Last year exh was told to pay £25 more a month, he threatened me with court and shared care so he 'didn't have to give me a penny'
In the end I agreed for him to keep paying the same amount
Fast forward to this year and he sent me a vile text saying the CMS is just punishment for hard working men who earn good money (he earns about 4 X what I do)
So he wants us to agree a monthly figure where I set out what I spend on the kids, not on housing, petrol or anything else as he doesn't believe he has any responsibility over those things.
Then when I've done that we split it 50/50 and he'll give me that.
One of the reasons I divorced him is that he was controlling and manipulative
I don't ask for anything on top of my maintenance, I work, I'm flexible re days and holidays, and we're amicable about everything apart from money as he really begrudges me it.
This text is causing me such anxiety as I know the threats and arguing will start again
Any advice would be great thanks
