Truthfully I'm less concerned about him in this situation than I am with them. By all I can see he was a good father, not the kind of toxic parent that people are better off avoiding. I'm worried about the burden going forward for the girls if he dies without them getting some resolution. I suspect their mother has filled their heads with lies.

I'm also, selfishly, not wanting to end up being that stranger that they blame for his death - people do weird things when they grieve. What if they second-guess his medical decisions and decide I'm to blame?

I have thought about getting him to keep a journal, writing to the girls. At least that way if they don't reconcile I would have something to give them after his death.

But I don't think he will paint as dire a picture for them right now as the situation really is, and I wouldn't want them to miss out on seeing him just because they're young and still think their father is invincible.
