Our DM died last year. During her final illness my DSis, who doesn't work/have children, was wonderful. I really appreciate what she did and have told her so. My DF is 87 and physically frail although mentally very sharp. He has been very lonely since Mum died and I have asked him if he wants to move in with me. I am a widow and currently live with DD2(23) and her boyfriend(23). I work, as do DD and bf, but they work NHS shifts and I am a teacher and so am here at weekends and school holidays. I also have a cleaner/dog walker who comes in twice a day so dad would seldom be alone for more that a couple of hours.
I have got a builder to install a wet room so dad will have a bedroom, sitting room and bathroom for himself on the ground floor although it is part of the house not an annex.
My DSis is really angry with me for offering without asking her permission. Dad wants to move in but is worried about offending her because she is so upset. I genuinely did not mean to upset her, it is impossible for Dad to live with her because her house can only be accessed by a flight of steps. Was I unreasonable not to ask her permission, she knew I was having the wet room installed for dad but says she thought it was for visits,
