Good point ImStaying. The data came from the census, so it would be a decent sample size. However, when they ask why people were divorced, they only have the answers people give to go by and assume it to be the truth. I bet everybody who answered "infidelity" was a BS. My WXH would have answered "different values and interests" or something equally benign. Waywards are liars by definition, and half of every divorce due to adultery has a wayward. The article doesn't give the numbers, but I bet if you doubled the infidelity responses to account for the lying WS's, it would more correctly reflect the truth.
