“RHOBH”: Kyle Richards Breaks Down Proving Her Innocence to Dorit After Texting Her Estranged Husband PK (Exclusive)

Kyle Richards is reaching a breaking point.

In PEOPLE's exclusive look at the Jan. 21 episode of The Real Housewives of Beverly Hills, the reality star, 56, snaps after she's confronted for her ongoing friendship with Dorit Kemsley's estranged husband, Paul "PK" Kemsley.

Though the Housewives have a healing spa day on the schedule, their outing proves to be less than tranquil when Kyle breaks down into tears while explaining the private text messages she had sent to Dorit's husband.

"I want to say something then I'm leaving, I don't know how this all went so wrong," she says to the group as Dorit, 48, insists she sit down. "I don't want to [sit down], I really don't. I can't do this anymore. I can't do this anymore. I really can't."

With tears in her eyes and veins protruding from her forehead, Kyle addresses Dorit. "I love you and PK and your kids," she says. "And you know that, I know that you know that. I've been made to feel like I did something wrong, you know, sending a text PK, so I said, I'm gonna read this once, and that is it."

After noting that Bozoma "Boz" Saint John made a "weird" comment about her intentions, Kyle reiterates she has "nothing to hide" and volunteers to read her message to the entire group.

"He makes a joke in April. The next text is not till the day you guys got separated," she says before reading off her phone. "I said, 'I know you have a lot of friends, I'm also one. If you need me, I've never repeated anything you've shared with me and wouldn't.'"

Kyle then clarifies that she didn't mean that she would actively hide things from Dorit, should PK choose to confide in her. She gestures to the cameras surrounding them and claims she meant she wouldn't share private details with production while they were filming the hit Bravo show.

Despite her emotional declaration, Garcelle Beauvais isn't convinced and points out a few holes in Kyle's confession in a conversation with cameras.

"I don't get what her talking to PK has to do with production," Garcelle, 58, explains. "So if you're having a private conversation with someone and you want to say, 'I will never share what we talked about with production,' you would write 'with production' — and she didn't do that."

"Either way, it doesn't look good because obviously, that means it was more than memes and jokes. Because if it's memes and jokes, share 'em! Production likes to laugh too," she adds.

Kyle's breaking point comes after she accused Dorit of being "way too touchy-feely" with her estranged husband, Mauricio Umansky, in last week's RHOBH episode amid the texting drama.

"There was a whole rumor about how Dorit has a thing for Mo, and it was all over the internet," she said. "She had to go and defend it and this and that. So don't even get me freaking started about sending stupid memes, okay?"

Later in the episode, Kyle told her costars she refused to be cornered and have to defend herself, saying: "The fact that she's trying to make it seem like I'm [doing] anything inappropriate is gross. And I'm not going to get to a point in my life where I am having to pull out my phone and s---, because I'm an adult, and that's a f---ing joke."

But when she read their texts aloud to the group, they also appeared bewildered by the confession. "Wait a minute, this is not just about memes and jokes. This is serious talk," Sutton Stracke told the cameras while Garcelle added, "So they have shared things about Dorit or [their] relationship ... So it's not all true."
