The CMS managed to track him down a few months ago so I've been receiving £15 per week, per child (we have 2 so £30 per week in total) for a couple of months now.
It's not much of a contribution really.
Last week was youngest DC birthday and he promised to contribute to birthday bike. Had to hound him for that and got a "fuck sake" before he paid the last instalment to me on the day of birthday.
I've sent him the screenshots of uniform bits DC needs (from Asda) but he's blanking me completely.
AIBU to ask for a contribution or is he right to be outraged that I'd even ask?
