AIBU in thinking this is the cheekiest thing you've ever heard? We take all the kids in our blended family on holiday. I personally have spent a lot of money on this in the last five years as I'm the main earner. Not a problem at all. Now DHs ex and her new DH wants to take the whole family away on a very expensive long haul holiday, and thinks we will be paying half. I have never heard of anything so ridiculous. I said I'd write her out an invoice for the ones we've had already in that case. And the two we are planning this year. 🤣
