Journalist Cassandra Thorburn launched her new podcast about divorce and separation on Wednesday night, where she spoke about divorce and separation.

The first episode of Divorce Story: Surviving Separation ,Thorburn went into the “grief” she felt after her split from former husband Karl Stefanovic, but insisted she is not in love with him.

Thorburn spoke to psychologist Jackie Manning, where she revealed that she isn’t in love with Stefanovic.

“People often say, are you over them? Yes, I am over them.

“I am over my ex-husband but it is about going through the grief of going through a divorce. Going through a divorce is really stressful, so that is something to grieve.”

Thorburn explained that divorce is a “trauma”.

“Divorce is a trauma, it is something you have to go through a process of. You can't underestimate that someone going through grief has to go through a process and if they have had a trauma.

“You can't limit that amount of grief... Your own grief process is your own”.

Thorburn and Stefanovic share three children, Jackson, 20, Ava, 14 and River, 12.

She also went into the difficulty of “starting over” after two decades of marriage and being a family.

“I had been with my partner for 21 years, had three children but my relationship ended and all of a sudden I found myself a single stay at home mum,” she said.

Thorburn got candid about how she deals with difficult conversations with Stefanovic.

“Things are said or written or texted or emailed or however you have that relationship with someone that was once a spouse,” she said.

“You can't take all of it to heart. You can often treat those closest to you the worst. You can say things that you wouldn't be able to say to someone else.”
