Would welcome your thoughts on this one: partner is currently out on work christmas party. We have a two year old and a 19 week old baby. I don't object to him going out for the evening however rather than coming home or staying at my parent's house he has booked himself into the Hilton for the night. He didn't want to stay with my parents (which would have been a short taxi ride to get back) in case I also stayed there with toddler and baby and he might have been disturbed in the night/asked to do something. He claims we discussed this which we definitely didn't. He mentioned it about a month or so ago and then we were probably distracted by toddler throwing something or something similar but I definitely didn't agree to it. He could have got a train and bus home or stayed at my parents, or I suppose booked a cheap room at the Travel Lodge but instead chose to stay at the Hilton so he can have a good nights sleep, nice breakfast and a jacuzzi in the morning before going into work (probably late). AIBU to object to this?
