Ex h and I have been separated for 2 years. We have 3 DC.
He pays £200 maintenance per month. This was settled through the CMS a few months ago.
Prior to this he paid me much less as he wasn't completely honest about his salary when we first worked out maintenance. It turns out he underpaid me by over £1000 which I know I'll never see.
So anyway I had to buy DD's secondary school uniform the other week which came to over £250. He is refusing to go halves and is not responding to my messages.
With big things like this we used to go halves, but he's now refusing.
Aibu or is he?
