ExH and I have a 9 year old together. Since we separated I've studied for a degree but I didn't ask him to contribute towards childcare then because I received a grant from university. From September my 9 year old and 5 year old will be attending different schools because 9 year old is being bullied, hates her school and desperately wants to move. 5 year old is settled and happy and doesn't want to move, nor is there a space for her and there's unlikely to be any time soon (12 people ahead of her on the list.)
ExH agrees that DD should move schools. However, both schools start and finish within five minutes of one another and are five miles apart. Therefore, I will have to use the before and after school club for DD9 which will cost £8.50 per day
ExH is not willing to help with any school runs at all despite being able to. Aibu to ask him to pay half of the childcare costs as he needs the childcare as well as me, even though he pays (minimal) maintenance?
