Kate Legge

In 2007, journalist and writer Kate Legg followed her husband into the garage of their family home where he broke the news that he'd been having an affair.

Greg and Kate had been together for some 30 years or so.

They'd had children together, a life together and they'd shared a career in the same industry.

Kate wrote that she flailed around for a while and then she recovered.

And then she got interested in the whole business of adultery, infidelity, having an affair, breaking the monogamous contract, whatever you want to call it.

And so in 2019, Kate invited him to join her on a road trip to Broken Hill in New South Wales.

to investigate his family history of infidelity, a history where infidelity had recurred over many generations.

And this investigation led Kate to look back at her own family history.

Kate's written a book about this.

It's called Infidelity and Other Affairs.

Hi, Kate.

Hello, Richard.

You're still married to Greg now, even though you're no longer a couple.

You've got separate partners now.

How would you describe your relationship these days?

Well, he's still pretty much my best friend, I'd have to say.

I always ring him when I've got a knotty problem to solve and we've got grandchildren together and so we've really tried to put our big people's pants on and channel our best selves and we get on very well.

We both share an interest in current affairs and both journalists together and we have so much in common but we are married still.

We just haven't bothered to get divorced but we both have different partners and, you know, we get on very well.

So it's a genuine friendship now, is it?
