Basic is I have a moral dilema.
Father recently diagnosed with a life threatening illness. Estranged older half sibling (same father).
Do I tell estranged sibling or not?
Father not well enough to ask. Acts tough but obviously still bothers him.
We are all estranged from older sibling so would mean reaching out. After years and years.
Last contact 2ish years ago after death of grandmother.
I'm torn. As middle child and only one who remembers older sibling.
