I left my ex 2 years ago after his continued angry and abusive behaviour got too much for me and he left the family home. I bought him out and he now has his own place and sees the children EOW, his choice.
The issue I have is maintenance, I earn fairly well and don't need his money to survive but so does he and he thinks he is paying me to look after his children. He turned into a weird MRA when we first split and claimed poverty so he pays nearly £200 less than CMS expects.
So far this year he has been on 2 long haul holidays and has another one booked (without the children obviously), has bought a new car (outright he told me) as well as a sports car, he is always out in very expensive new clothes which he brags about when I pick up the children as well as claiming he has 1000s in savings. I don't care what he does with his money or time this is just for context.
I am trying to break free a bit as he has been very enmeshed with my life still, insisting he comes and fixes things for me etc. whilst I have been grateful I don't need him to do it but wanted to stay on the right side of him for the children.
The other week he bought the children home and shouted at me for ages about something insignificant. I stuck up for myself and have grey rocked him, this has not gone down well.
I did ask him for a contribution to the school uniform costs (nearly £350) which he agreed to but when I text him his half he has gone mad saying how he is so very poor and he hasn't reduced maintenance and that I need to shut the fuck up moaning about money to him.
I guess my question is, should I just go to CMS, this will go down terribly with him or suck up the £200 less and extra costs and just ignore him from now on. I'm at the end of my tether with him, he's just so needlessly mean, I don't know why I expected anything less. I honestly don't know how to coparent with him.
