Everybody makes mistakes. For "Jersey Shore" star Jenni 'JWoww" Farley, one of those mistakes turned into her biggest regret.

During Thursday's episode of "Jersey Shore Family Vacation," Jenni opened up about her divorce from Roger Matthews, which at the time had not been finalized despite it being nearly a year since she filed.

"We were talking about regrets earlier — I’ve been thinking about the biggest one," she told her best friend Nicole "Snooki" Polizzi during a heart-to-heart, as reported by People.

“Roger?” Nicole asked.

"Yeah," Jenni said, "I’m going through it with the divorce. It’s been almost a year since I filed. When you get divorced, you’re supposed to be celebrating and start a new chapter, but it’s really heartbreaking. And it’s stressful, the up and down battle of figuring out custody issues. I just don’t know when it gets better. It’s more than exhausting."

"...It can mentally break someone," she added. "I just want peace."

"He’s the [expletive] worst," Nicole said. "But you always knew it wasn’t right."

Thankfully, the mother of two can put that situation behind her now since her divorce was finalized in August. These days, she's busy trying to navigate a relationship with her younger boyfriend, Zack Carpinello and her roommate, Angelina Pivarnick.

Jenni accused Angelina of kissing her boyfriend, and although the two "Jersey Shore" castmates came to an understanding during the episode, their feud was reignited when the footage of what really happened aired on October 24. However, this time, the squabble was over Angelina's "joke" about having a threesome with the couple.

"Jersey Shore Family Vacation" Season 3 airs Thursdays on MTV at 8/7c.
