Do you know why your dad stopped loving your mother?

[Answered by Caroline on Quora.com]

He didn't. They were together for over 60 years. After his death, she found a folder in which he had painstakingly put together a guide to everything she would ever need to do after his death. Not just the funeral stuff but what bills needed to be paid and when, how often to test the smoke alarm, people's birthdays. Literally everything. This may sound a bit patronising but my mother, while a lovely woman, had no idea how to change a light bulb. He was a kind and devoted husband and I am proud to have been his daughter.
