If your new man was going to be working with the home wrecker who took away your husband, what would do? That dilemma may now be facing the lovely Reese Witherspoon, who, post-divorce from Ryan Phillippe, is seeing Jake Gyllenhaal.

In Touch Weekly says that Abbie Cornish — the actress whose affair with Ryan Philippe caused the end of his marriage to Reese — may be cast as Jake Gyllenhaal's love interest in an upcoming film.

Of course the natural instinct would be to say to Jake, "No way do I want you to act in that movie with her." But getting roles in Hollywood is not as easy as finding the latest Fendi bag, and directors make casting choices, unless the actor is a major A-lister. Witherspoon is in that league; Gyllenhaal is not.

And in that line of work, many relationships are created by on-set romances. Angelina Jolie met two husbands and her current amour — Johnny Lee Miller, Billy Bob Thornton, and now Brad Pitt — while working on films.

Robert Rodriguez left his wife after meeting Rose McGowan; Russell Crowe had an affair with Meg Ryan, causing her to break-up with Dennis Quaid; and Reese met Gyllenhaal while doing the movie Rendition.

That, of course, is one of the perils of that business. Few other places have you kissing strangers passionately as part of the job requirement, or going off to an exotic location for months, away from family and spouse.

But many people meet their future spouses at work. In an Elle/MSNBC poll, two-thirds of the 31,000 people polled reportedly flirt at the office.

But take heart, that your heart may not be permanently broken. Flirting is flirting.

Only 55 percent of office relationships turn into marriage, according to the Society of Human Resources Management.

Best solution for Reese if Cornish does get that role with Gyllenhaal?

She should manage her own schedule so she can be close by. As long as she is radiating that beautiful smile and exhibiting her beguiling charm and smarts, Witherspoon will remind Gyllenhaal why he chose such a class act.
