"At the end of the day, I'm going to fess up. I looked crazy and Jamie, if you're watching this right now, I'm sorry," Elizabeth said during a Wednesday appearance on Married at First Sight: Unfiltered.
Elizabeth watched back a Season 9 clip on Unfiltered in which she had accused Jamie of "dragging" her dogs on their walk and Jamie had therefore taken responsibility for not "walking the dogs correctly."
But Elizabeth was still furious and threatened to leave the apartment, which prompted Jamie to say he'd want a divorce if she chose to leave.
Jamie said he was following the advice of Married at First Sight expert Dr. Pepper Schwartz, who had previously asked the couple never to walk out on each other during an argument.
Ironically, however, Elizabeth's two dogs were cuddled with Jamie on the couch when they were having this argument.
When Elizabeth was asked on Unfiltered how she felt when Jamie gave her an ultimatum, she replied, "I didn't take it serious."
"To be really honest with you, I knew Jamie didn't want a divorce," Elizabeth said.
"It's just, like, I have to make fun of that now. Right now, seeing it, what I was even saying out of my mouth -- I was just jabbering. And if I were Jamie, I would probably be the same way too. I don't even blame him for that."
Elizabeth then laughed about how her dogs were all over Jamie in the moment.
"That makes me look so bad now!" Elizabeth yelled with a laugh. "My dogs are like, 'What are you talking about, mom?! Dad's forever. He's going to be with us forever.'"

Jamie has said repeatedly on Season 9 ofMarried at First Sight that Elizabeth struggles to admit when she's wrong and say sorry, but she apparently had no trouble owning up to her mistakes on Unfiltered.
"To me, it's actually funny -- the banter that goes back and forth between you guys. But just knowing and talking to Jamie a couple of times, he really does take that stuff seriously," Iris warned Elizabeth.
"He takes it to heart, so just be cognizant. That's all I've got to say," Iris added.
Matt then offered his take on Elizabeth and Jamie's argument over the dogs.
"I think they have a very happy, positive, functioning relationship. And I'm happy for them," Matt said sarcastically before bursting into laughter.
Elizabeth also couldn't help but laugh at Matt's comment.
"That was the best back-handed comment coming from your chopping block," Elizabeth told Matt playfully. "So, thanks."
This is not the only fight Elizabeth and Jamie have gotten into on Married at First Sight. The pair claim to be in love with and crazy about each other, but they fight constantly, and they don't exactly fight fair.
Dr. Pepper has been shown telling the spouses they throw harsh words out to hurt the other person.
Jamie has criticized Elizabeth for working underneath her father and called her "a materialistic c-nt" in the most recent episode, while Elizabeth has accused Jamie of being mean, negative and "a sexaholic" who's boring in the bedroom.
There's never a dull moment with these two on the Lifetime reality series!
