I’ve had this too. I actually prefer being able to leave and go back to my own space anyway. I just don’t stay at other people’s houses any more.Years back, when me and my husband went to stay with certain family members it was often assumed that we'd sleep on the sofa/sofa cushions on the floor/airbeds etc while the people with kids got proper rooms and beds. I often felt like we were seen as not 'proper' grown ups so we'd be happy to make do.
With those family members we started booking our own hotels or B&Bs instead and gradually the visits have tailed off. Thankfully!
