Thank you all for your kind comments. As this thread wraps down, I just want to say it is not about me and any "character" I may or may not have. It is about listening to someone who was telling me something I would rather not hear and then, despite denials about what he said, acting on it as it was relayed.
Our whole lives have pivoted on how I reacted to his comments. I could have ignored them and spent years vilifying my former wife, trying to poison our children against her, and she could have spent years defending herself and attacking me. We both could have spent those years trying to be "right", but doing that would have done irreperable damage to our children. The kids could have had to play games trying to be nice to me and humoring me as I told them how rotten their mother was, and then when they were with her, they could have been forced to play the opposite game. Gee, I would have felt good and vindicated, and gee, she would have felt good and vindicated. The kids would have been confused, torn and felt terrible and even miserable, and even could have made decisions that would have hurt either their mother and me or both and hurt them all for life. Not to mention me and their mother.
By the way, the man who pointed out my idiotic thinking was not even a best friend at the time, but a "good" friend. He did talk me out of jumping off the Coronado Bridge into the San Diego Harbor (a 99% guaranteed suicide) after I was already on my way to do it all those many years ago. Before I jumped, I pulled off the freeway to say goodbye to him. He said I should go out dancing and that he would buy me dinner, so at least I would have had a good time and a full belly before I croaked. So like the fool that I am, I took his advice. I'm still here. So, yes: he not only became a best friend that night. He saved my life. And he also saved my family. I am blessed for people like him in my life.
