The mother-of-two has denied she wants her former husband to go to jail as Nine newspapers, seeks to prove allegations the war hero is a war criminal.

On the stand for a second day, Ms. Roberts denied she is a scorned wife out for revenge.

The defamation trial was read text messages about her nasty split with Mr Roberts-Smith.

Her best friend Danielle Scott told Ms Roberts that once she becomes financially independent of her ex-husband, “then it doesn’t matter what happens to him or what jail cell he rots in”.

Ms Roberts described the father of her children as a “lying, cheating, —- human” and ended another text with the word “#Titanic”, referencing the sinking of the famous ship.

She was then grilled about giving evidence for Nine newspapers.

“You’d like to see my client lose this case, wouldn’t you?” Bruce McClintock, SC, asked her.

“No… I hope Ben survives this nightmare,” she responded, adding: “I would not want Ben to go to jail.”

Ms Roberts admitted to meeting with journalist Nick McKenzie weeks before an episode of 60 Minutes claimed the decorated solider buried a lunchbox of USBs in his backyard to hide classified defence files.

The mother-of-two has refuted suggestions she dished the dirt on her ex-husband or leaked the damaging photos of SAS members drinking from the prosthetic leg of a dead Afghan detainee.

For two days, the court has focused on the tumultuous personal life of Mr Roberts-Smith.

Tomorrow the case will again focus on Afghanistan as another specialist soldier is set to give evidence.
