Not any wives I know. Before, during, or after that film, most wives I know who caught their husbands cheating kicked the bum out fast. If my wife ever caught me, I'd be the one boiling in the pot.
Hell, as popular as that film was, only a relatively few people watch it on a percentage basis, and I don't know very many women who even liked it.
You're giving way, way, way too much credit to this film, and certainly aren't looking at the hundreds of thousands to millions of marriages that broke up because of infidelity long before the film was ever made.
Seriously, I never, ever met a woman who thought that way before Fatal Attraction. I do know a lot of women who kicked their husbands out for cheating, even when the cheating didn't go all the way to sex, long before FA.
