Just watch any of the crap on TV that celebrate Wives leaving their Husbands and Family to “experience life” - The wife who leaves in most of these made for TV movies lives in an upper class suburb - drives a $75,000 SUV and has a very good life - except she made the terrible mistake of getting married and have kids.
2009's One Hot Summer has a similar theme and plot. Wife has an affair. Husband never learns of it. But wife is now a better woman because of her affair, and a better, sexier, more happy wife to her husband.
The morale: Woman, when you have an extra-marital affair, you're actually doing your husband a favor. You're improving yourself, becoming a better wife and lover for your husband.
