Can any tell me any info., about end stage liver desease?

the doctors said my nephew is in end stage liver disease,he is 56,in ICU,going on 3weeks. he has a Cathe, a feeding tube,a tube to his bowles, IV of meds to keep his blood pressure up and he was in a coma for a short time,sometimes he knows us and other times he doesn,t, he can,t sit up etc. now he is having kidney problems,and his stomach keeps filling with fluid and he has a drain hose from his lungs because of blood and fluid building up his doctors says he is to sick for a transplant. Our family has never dealt with this before and I believe his mother refuses to think he will not come out of it.Is he dieing ? I believe his organs are shutting down.He was in a small community hospital 100 miles from any family his doctor told my sister his mother there wasn't anything to be done for him and she had him moved here and talks as if they will save him.He has never been married his father is dead and he has one sister and his mother is 75 I am really concerned about her thinking and she gets mad if we try to talk about his dieing.So please give me any info., about this disease that you might have and thank you
