My DP has a DD who is 22 and like all parents, she loves her very much and is very proud of her achievments (University Degree, top job etc etc). DD lives away and DP will visit her at weekends and have days out together or DD will visit and stay the weekend with us which is ok because she can relax and away from a busy city but we always do what she wants to do i.e shopping, stay in or days out. Yesterday me and DP decided to go out for the morning and maybe lunch maybe not, but see what happens. When she told DD our plans she said she just wanted to go into town, which is what they did and I went out on my own.
There is no compromising with my DP her DD comes first every time. AIBU to be angry and annoyed.
