So it appears that Paul died a week ago. This is very sad but I'm also grateful that he did not suffer longer, it sounds from reading between the lines of the OP that it was a bad situation.
It is particularly sad because he was so looking forward to retirement in SC and enjoying life around his family. He had a son and daughter that are both doing very well in the world and in the prime of young life, bringing him lots of joy. It breaks my heart.
Maybe later when time allows, I will share some of my experiences with him. He was a great guy and a real "man's man," very fun to be around. We actually shared a lot in common, just not online politics.
He will be missed by so many.
