After 4 years I have finally put in a CM claim. Ex has also just dropped me in it by taking a job working away giving me no time to sort childcare (he has them 2 nights per week). He doesn't usually work much at all, so this is a bolt out of the blue. He has them tonight for the last time for 5 weeks. To date he has paid absolutely nothing, though does pay for ds1's cricket (minimal cost & doesn't contribute anything for ds2's activities.
I have just run a bath when I got a text saying that as I have decided to take his money despite earning 4 times more than him he will no longer pay for 'any activities'. I'm a bloody teacher, not a hedge fund manager. He earns fuck all because he's a 'musician' and won't 'compromise' on what he does. Apparently, as I haven't paid for cricket so far this season (I thought he had paid it - he's always there as he coaches, no one ever asked me for any money) I need to pay tonight or explain to ds1 why he can't go anymore.
I've replied to the effect of 'no', but now I'm wobbling. Ds1 is passionate about it, and why should he miss out. But I'm not sure it will actually come to that. Training is in an hour. I don't want to back down, and I don't want to have to go out again for any reason tonight. AIBU? What would you do?
