DD is 9. Her dad usually only sees her EOW but six weeks ago asked to collect her from school tomorrow and have her overnight because it's his birthday. I agreed and made plans with my two younger dc as we wouldn't have to pick DD up from school. These plans involve booking tickets and are a distance away that means returning to collect her is impossible.
Her dad sent me a text message this morning saying he's at work until 6 on Thursday now so if I could collect DD from school that'd be great, then his GF will collect her from me at 5.30. There was no asking, it was written as though this is what will be happening. DD has learning difficulties and doesn't cope well with change. His GF hasn't collected her before and she's previously become very upset when her dad has suggested it. I really don't want to cancel my plans with my younger dc but feel exH is forcing me to do so. He said if I don't want to cancel my plans then I can book her in the after school club and his GF will collect her from there. Firstly, DD would hate that. No one from her class goes and as I said up thread, she hates change. Secondly, I'm annoyed he thinks I should book it for him.
If DD goes to after school club (if they even have a space at this short notice/if they'd let his GF who they've never seen collect her) then she's likely to be out of sorts for days because of the change of routine which will be up to me to deal with. I've explained this to exH and he said that I should do as he's said and collect her then have his GF collect her from me.
I feel like he's trying to force me into either cancelling my plans or cancelling the contact. Aibu to say he needs to find a solution that suits all parties - particularly DD - and refuse to cancel my plans?
