Ex has DTs3 1 day a week and I knew he took them to his mums house.
Whenever I've asked questions about what did daddy make you for tea etc they've always said Nana made us X, that kind of thing. But I assumed their dad was also there.
Then Monday they got back and I asked them how it was seeing daddy, they said daddy wasn't there he was working, we didn't see him.
AIBU to think this isn't on? To take the kids on his day and palm them off on his mum and not even see them?
I texted him about it and haven't got a reply.
