I am always curious as to why people would divorce after 38 years. It says in the article he has Parkinson's. Would health issues, be the reason?
One of my uncles did the same thing. Apparantly, they have been having fights and he got tired of it all. My aunt held her head up with dignity, and proved she was a classy lady, by still treating him well.
This is so sad.
