How many marriages did he have? 2. First one 8 years and the last one was with Nancy for more than 40 years. But who are we to cast stones at him especially when he is advising his son privately. I mean, it's not like he is trying to advise the whole nation on marriage.

Here is something I pulled out of Wikipedia regarding his relationship with Nancy Reagan. Might give some perspective on his letter to his son.

"During his presidency they were reported to frequently display their affection for one another; one press secretary said, "They never took each other for granted. They never stopped courting." He often called her "Mommy" she called him "Ronnie". He once wrote to her, "Whatever I treasure and enjoy ... all would be without meaning if I didn't have you." When he was in the hospital in 1981, she slept with one of his shirts to be comforted by his scent. In a letter to U.S. citizens written in 1994, Reagan wrote "I have recently been told that I am one of the millions of Americans who will be afflicted with Alzheimer's disease.... I only wish there was some way I could spare Nancy from this painful experience," and in 1998, while Reagan was stricken by Alzheimer's, Nancy told Vanity Fair, "Our relationship is very special. We were very much in love and still are. When I say my life began with Ronnie, well, it's true. It did. I can't imagine life without him."
