'Real Housewives' star Erika Jayne says her estranged husband, Tom Girardi, drove off a cliff and was 'unconscious for 12 hours' in 2017

• Erika Jayne said Tom Girardi was "unconscious for 12 hours" after his 2017 car accident.
• She gave more details on Wednesday's episode of "The Real Housewives of Beverly Hills."
• Girardi is accused of embezzling millions from "widows and orphans" of plane-crash victims.

Erika Jayne is shedding more light on what she said were the tumultuous final years of her marriage with Tom Girardi.

On Wednesday night's episode of "The Real Housewives of Beverly Hills," Jayne, 50, told costar Kyle Richards that Girardi, 82, was "unconscious for 12 hours" after his 2017 car accident.

Jayne - who filed for divorce from Girardi in November and is named in a string of lawsuits against him - told Richards that she had kept her husband's condition after the crash a secret because she was "respecting Tom's privacy."

"I know, because I found him," said Jayne, who said Girardi also suffered a head injury, snapped his ankle, and broke his shoulder and clavicle in the crash.

Jayne said in the same episode that she had also assumed that Girardi, who was recently put under a conservatorship because of a "major neurocognitive disorder," was "with some other woman" on the night of the crash. She added that the famed personal-injury attorney had multiple lengthy affairs during their 22 years of marriage.

"I knew a lot, because it was so hard to hide, and, you know, he was sloppy," said Jayne, who added that she found evidence of Girardi's extramarital affairs through texts and photos on his phone. The reality star also said that when she confronted Girardi about his alleged infidelity, he didn't deny it.

"You guys have no idea what I've been living through, no idea what I've been through," she continued. "This is my life."

Shortly after Jayne filed to divorce Girardi, a December lawsuit alleged that the divorce was a "sham," and that the couple was using their split to hide money meant for the "widows and orphans" of plane-crash victims.

An unnamed source countered the sham-divorce claim, telling People in December that Jayne had filed for divorce from Girardi because "he was cheating on her with multiple women," and she had reached "her breaking point."

"The lawsuit just coincided with her decision to leave him," the source said.

But Jayne's legal problems are just beginning. Earlier this month, a judge ruled that the reality star is liable to pay three of her husband's former clients amid his ongoing bankruptcy case and accusations that he embezzled settlement money from them. Those clients are owed $11 million.

The motion comes after a bankruptcy trustee found that Girardi had transferred $20 million in loans from his law firm, Girardi Keese, to Jayne's company, EJ Global.
