So in the process of buying a new house with my partner. I have three children and he has one. The new house has 4 bedrooms. 2 good size and 2 smaller. He wants his daughter to have the second biggest room. She does not live with us full time, she lives with her mum. I don’t feel this is fair as my two youngest will have to share a room and now it looks like they will have to share a smaller room. This is totally grating me. He won’t budge on this as he says he’s promised her this room because she wanted it. I will be honest his daughter rarely gets told no. I guess it’s the joy of being an only child. I’ve really struggled with this as she has become quite entitled and really can’t handle if she doesn’t get her own way.
I literally don’t know how to handle this and tbh I’m dreading having to live with her - any advice would be greatly appreciated
