Credit Card Companies predict Divorce 2 years in Advance

According to the Vice President of google credit card companies can predict who is going to get divorced 2 years in advance - with 98% accuracy. What are their spending patterns?

Here's my guess:

Women

Plastic surgery
Weight Watchers subscription
Education and retraining - teacher training, social worker, mediators, TEFL
Gym membership
Nights out with the girls
Weekend away with the girls


Men

Alcohol
Hotels working away
Apps for phone and computer gaming.

I doubt that the spending pattern is of those committing adultery - many marriages survive this. It is of those growing apart....
