I was estranged from my own mother before she passed a bunch of years ago. At the time my wife pushed me hard to visit her in her last days and I refused. I didn't want a fake death-bed reconciliation. I loved and cared a lot about my mother but for reasons of her own that I never understood she shut her children out of her life for the last few years of it.
People don't live their lives the way that we think that they should. And even during times of crisis, when people should be reaching out to family etc, well, sometimes they don't too.
After my mother passed my family and I did attend the "celebration of life" and funeral and did our duty. But that was more for my brothers and sisters and to show an example to my children.
My own opinion is to let CMM do things the way that he wants to. A possibly painful time with his daughters is probably not what he wants at this time.
