What you said about H becoming an atheist struck a chord. My W also lost her faith, and things really changed around that time. Granted, she was going through a lot physically, but it makes me wonder. I went to a wedding last summer, and the priest mentioned that in couples that worship together, divorce is very, very rare. I can't confirm the accuracy of that statement, but if it's true, it helps put things in perspective.
