So until recently I have driven 200m round trip to drop off DC's to My ExH so that they can see him because he doesn't drive. He paid petrol money. I now can't make the trip due to surgery. I have advised ExH of this with plenty of notice. He has now asked if he can sleep on DC's floor on his weekends. I have asked him to get the train and he says that IBU. Our divorce was over 10 years ago but it wasn't the friendliest. Oldest DC's not fussed about seeing him as he lets the youngest get away with murder and tells the others off for upsetting him, making them miserable all weekend. So AIBU to ask him to get the train?
