Hi, my stepmum has terminal cancer and is in her last days (told by the hospital).  She has been allowed to come home to be in as much comfort as possible and to spend this remaining time with her family.

However she has not been told exactly how long she has.  My father is her primary carer; they have had a happy marriage for 40 years and he has not been told how long they have either.  All they know is that there is nothing more that can be done for her.

My sister and i know that she likely has a week at most so we are both off work and trying to spend time with them.

Our problem is that my stepmum is basically verbally abusing my father.  He is on the verge of tears and trying to care for her in every way.  She will not accept help from anybody else, including carers, however nothing my dad does is right and she is constantly having digs at him and putting him down in front of us and so they are arguing.  She is permanently on oxygen and cannot move anywhere so needs help with everything. My dad is trying to be patient and understands its the cancer talking.  This is so so hard for us to witness.  Do i tell them it's their last few days so they can try to have nice memories and ease up on the arguing etc?

Has anyone else experienced this?

Thank you so much for any advice!
