Nobody ever cats around on his or her partner in an upfront, honest way. They never do it with permission or pre-affair clearances. The horse always comes before the cart. Nobody ever says to his or her partner “I think we need to be apart for a while and decide what we really want” and then falls for someone else. 99% of the time the hunka chunka comes first, and then the cuckold smells it and accusations ensue, etc.

In a 1.8.21 People piece about the recent romantic triangle between the now-together Olivia Wilde and Harry Styles and Wilde’s cuckolded partner Jason Sudekis, Alexia Fernández and Melody Chiu report an old familiar tale…same as it ever was.

It all happened during the shooting of Wilde’s Don’t Worry, Darling, which Wikipedia describes as a “psychological horror film” set in the 1950s.

Excerpt: “While an insider told People [last] November that Wilde and Sudekis had split ‘at the beginning of the year‘ after seven years together, another source with knowledge of the situation refutes the claim, saying ‘Olivia and Jason were very much together as recently as [last October].”

Wilde fired the film’s lead actor Shia Labeouf (poor behavior, clashes with crew members) and replaced him with Styles. An affair between Styles and Wilde ignited fairly quickly once shooting began. The usual hints and signals were generated, and Sudekis gradually got wise.

People again: “Jason [explains] that the timeline that Olivia and Harry would like people to believe—that she and Jason split ages ago, long before she became involved with Harry — is simply not accurate,” says [a] source.

“She began filming Don’t Worry Darling in [the early fall], and by October, Sudekis began to get the impression that she wanted out. By November, they’d announced their split.”

And that, says the source, “is how quickly it happened, and none of it happened until she began filming with Harry.”

Any relationship counselor will tell you that infidelity is sometimes as much of a symptom of relationship troubles as a cause of them.

Then again sometimes a married actor will simply conclude that a certain costar is a hotter, more desirable partner than the person he/she is married to, as Brad Pitt apparently decided when he began cheating on Jennifer Aniston with Angelina Jolie.

Or when Elizabeth Taylor dumped Eddie Fisher when she fell for Richard Burton during the making of Cleopatra.

Or when Meg Ryan betrayed Dennis Quaid when she and Russell Crowe had an affair during the filming of Proof of Life.

Any way you slice it there’s no neat and tidy way to break up with your spouse after you’ve catted around behind their back. Especially with People and Hollywood Elsewhere writing about the blow-by-blow. Always messy, always hurts.
