DD spends consequtive 7 nights a fortnight with her Dad - she comes to me after school on school nights, he picks her up from here after work and drops her at school the next morning.
Her school disco is coming up, on one of the evenings she's with him - so I emailed exH and asked that he pick her up from there an hour and a half later than he usually picks her up from me.
He's sent me a snotty email back telling me that he will 'comply' this time, but 'requesting' that I not make arrangements for DD in 'his' time.
Should i leave it up to him to book/arrange these things? I'm responsible for paying for school activities (I get child benefit and child support) if it makes a difference?
