Erika Jayne said husband Tom Girardi's personality 'completely changed' after he drove off a cliff and was unconscious for 12 hours

• Erika Jayne revealed new details about the car crash that left Tom Girard unconcious for 12 hours.
• Jayne told her "Real Housewives of Beverly Hills" costars that his personality "completely changed."
• Girardi and Jayne are accused of embezzling millions from the widows of plane crash victims.

Erika Jayne is sharing even more details about Tom Girardi's serious car crash in 2017.

On Wednesday's episode of "The Real Housewives of Beverly Hills," Jayne said that her estranged husband Girardi's personality "completely changed" after the accident.

"Three years ago, he had a terrible, terrible head injury and there was a significant shift in his personality, his decision-making, and who he is," Jayne told her costars Garcelle Beauvais and Crystal Kung Minkoff.

Jayne, 50, revealed in a previous episode that she found Girardi, 82, after the crash, telling costar Kyle Richards that he had suffered a head injury, snapped his ankle, and broke his shoulder and clavicle.

Beauvais asked Jayne if she filed for divorce from Girardi in November because she knew they'd be facing a wave of lawsuits, including one that claims the personal-injury attorney and reality TV star embezzled millions from the widows and orphans of plane crash victims to fund their lavish lifestyle.

"No, I did not," Jayne said. "This was a long time coming."

Jayne told her costars that after the crash, Girardi lost the ability to even hold a normal conversation.

"The conversations that I used to have with him - the back and forth - was no longer," she continued. "The repetitive phrases, the forgetting what we were talking about; I would hear the same stories 10 times in one day."

Jayne then said that she believes Girardi - who was recently put under a conservatorship because of a "major neurocognitive disorder" - never intentionally tried to hurt anyone.

"Part of true brain trauma is making decisions that you wouldn't normally make," she said. "It's hard to watch someone go through this and there's nothing I can do to help. I tried. He didn't listen. He's resisting everything."

Shortly after Jayne broke up with Girardi, a December lawsuit alleged that the divorce was a "sham" and that the couple was using their split to hide money meant for his clients.

In July, a judge ruled that Jayne 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.

Jayne told Beauvais and Minkoff that Girardi still calls her every day, but that she hasn't spoken to him since she filed for divorce and moved out of their $15 million mansion in Pasadena, California.

"I have not talked to him and I cannot talk to him. Even though he calls me every day," Jayne said. "That's another hard part of it. I had to ask my attorney to call his attorney to say, 'Please stop calling Erika.'"

"You know, it's just horrible. 'I love you, I miss you, come home, are you sure?' I'm like, 'Stop. You gotta stop, you have to stop, honey. You need help.' And I can't give it."

"The Real Housewives of Beverly Hills" airs Wednesday nights at 8 p.m. ET/7 p.m. CT on Bravo.
