I was going to take my 3 kids to visit my sister at her house for a few days (leaving my husband at home with our dog) but then thought it might be more of a break to go away to an Airbnb with my sister and her 2 kids. I found a suitable Airbnb that fit us all in, in a nice location and my sister was keen. However, her husband is now objecting to this arrangement and feels it is the most unreasonable suggestion he has ever heard to exclude him from a 3 night break. I don’t think it’s unheard of for one parent to take their kids away for a few nights but he tells me I am being unreasonable. So AIBU???
