She found out her boyfriend of 4 years was actually married with kids.

There was one morning radio segment that had everyone in the Mamamia office talking this morning.

It was the story of a woman whose partner of four years had suddenly vanished without a trace, and it came via Chrissie and Jane’s Private Investigator on Mix 101.1.

For those of you who haven’t heard of Chrissie and Jane’s Private Investigator, it’s a weekly segment where the show’s P.I. looks into listeners’ long lost family members, suspicious partners and, well, anything else that might make for good radio.

This morning, the person under the microscope was Marie.

Marie’s partner of four years had suddenly vanished without a trace. One moment they were discussing marriage, babies, and moving interstate. The next, he had completely cut contact and disappeared from her life.

Not surprisingly, she wanted to know what was up.

Marie lives in Melbourne and had met the man online. He also lived in Melbourne, but said that he could never stay the night because of work commitments in Adelaide. This was despite the fact that they saw each other almost every day for four years.

He made promise after promise of marriage and exotic holidays, but never followed through.

Then one day, this mystery man told Marie he had terminal cancer of the lymph nodes, kidneys and pancreas.

The last time Marie heard from him was June 13, when he told her he’d run out of phone credit.

Then, nothing.

In a bid to “find some answers,” Marie asked the Chrissie and Jane Show’s Private Investigator to do some digging. And what they discovered floored her.

The guy was alive. He didn’t have cancer or any other kind of illness. He lied about working in Adelaide – the real reason he could never stay the night with Marie?

HE HAS A WIFE AND KIDS.

He had also lied about his age, even his name.

“My life, I have told him everything. I have never kept anything away from him. Nothing’s secret with me. And this asshole has lied to me from day one,” Marie said.

“Wouldn’t you think the wife would suss something out as well? To do that sort of thing, why would you? How could you?”

Totally understandably, Marie’s been left gutted and heartbroken. And she can’t even call him and scream, because he’s thrown away the phone he called her on.

At the very least, she knows, and can start to rebuild her life.

And yet. There are two women involved here. This guy is the ultimate Catfish. He created a fake identity, found a woman online, and led her on for FOUR YEARS. All while he had a wife at home. And while Marie, the unwilling mistress –  now has the chance to move on, what about ‘Mr Right’s’ wife?

Doesn’t she have the right to know what her husband has been doing? Or is it nobody’s place to tell her?

How would you handle this situation? If you found out someone was cheating, would you tell their spouse, or stay the hell out of it?
