Kids (shared DC 3 +4 and husband's two eldest 8 + 10) were supposed to go to a Halloween party tonight at my relatives, they do parties for all sorts of stuff and love hosting things! The kids were really looking forward to it.
Unfortunately relative tested positive for Covid yesterday so has had to cancel. Because all the DC were really looking forward to going I went and bought decorations, pumpkins to carve, party food, sweets etc.. so we could have a party at home.
My husband's ex has a habit of just telling us what's happening she'll decide X and assumes we shouldn't get a say. She's decided that as we aren't going to the party anymore she wants DSC back so they can go trick or treating with her youngest ones.
When we've said we have bought pumpkins, decs and food she's suggested we and the kids with some of it to her house.
The kids hate getting involved and will just tell each parent what they want to hear i.e. 'i don't mind staying here' to us and 'i don't mind coming home' to their mum. She has form for always doing this, her way or the highway.
AIBU saying if the kids go back to hers there is no way they are taking a load of party stuff with them for her and her other kids to use too. We'll just have a party with our kids and have left overs.
Husband hates arguing with her so thinks it's not a big deal sending them with pumpkins and food/sweets/some decs if they want to go back. I bought it out if my own pocket though so it's up to me.
I think if you want to insist on having the kids back fine but spend your own money then.
