Linda,
I understand how difficult it is to see the personality change and you your husband and his sister are trying everything to help (use $$ from house for transplant, etc). I would have been heartbroken had my husband passed away while he was so hateful (totally out of character). It would have been really hard to live with thinking I could have done something to change it.
So I really understand that. This summer when I would complain to my Mom (86 years old) about how hateful he was being, she would say "HE"S SICK" "YOU DON"T GET IT, HE"S SICK" By that what she meant is that I can't take his behavior now and look at it like this is who he is..."HE IS SICK" So I'm paying that bit of advise forward. "HE IS SICK", and it may be someone else that is feeding him info about what "baddies" you are, and he can't sift the truth from stories now with the HE and the meds.
{I think it would be easy for me to turn my husband against his family if I were so inclined ...WHICH I AM NOT...but he is so vulnerable to whoever is taking care of him and what they tell him, and suffers from cognitive problems.}....just say'en.
Hope that you all just keep trying to keep in touch with him. JUST A THOUGHT. Doesn't sound like you all have the best relationship to BIL's wife, BUT...if she is caring for him at home, she is overwhelmed and is probably on the receiving end of his personality change herself. I thought I was a very strong independent professional woman, but after months of taking care of Hubby with ESLD and nasty attiutude, doing all work around house, caring for pets, and trying to get all bills paid, while trying to get hubby qualified for funding for transplant, and Dr. appts, etc, I was a basket case.
Hubby's family, who I really like, but live along ways away, called and wanted to know if they could send something to help. I asked fthem to send an electric razor for him (he took them all apart for some reason). This was in August, and on his Birthday Oct 19 they send a razor. I know this was a little thing, But I was so hurt that it took them that long to do it, when I felt I was drowning and only asked for one little tiny thing. Anyone, just the perspective of a worn out exhausted caregiver. May not relate to her or you all, but it is hard to understand how truely worn out and alone caregive can feel.
Best to you and keep posting. I am lighting a candle tonight, but to help keep warm, It's supposed to be -10 degrees and 40 mph winds. Cold enought to freeze pork solid !! Porksycle !!
