Tom Schwartz won't go down with this ship—or at least he's hoping he won't. 

The Vanderpump Rules star recently reflected on the continuing fallout from the affair between costars Tom Sandoval and Raquel Leviss, admitting that the controversy—and the criticism he's received over his part in the matter—has taken a toll on him.

"It's incredibly messed up," Schwartz said in a confessional for the upcoming June 12 episode of Fox's Stars on Mars. "But the thing is I've become mired in it."

He continued, "It's been a huge source of angst in my life. I've been in this extended funk."

The 40-year-old, who is on the reality show where celebrities experience what life would be like as astronauts on Mars, told fellow contestant Natasha Leggero that he feels Vanderpump Rules makes viewers feel better about their own relationships when they watch the "train wreck that is sometimes our lives."

Schwartz also spoke to his own role in the affair, which he described as torrid.

"It's horrible and I feel complicit," he reflected  on keeping the affair from his BFF and business partner's then-girlfriend of nine years Ariana Madix, "because I didn't cover for him, but I had his back. He came to me and confided in me that he was in love with someone else." 

In the clip, Schwartz also opened up to Natasha about his divorce with Katie Maloney, who he split from in March 2022 after a decade together.

"I'll take most of the responsibility for that," he confessed. "But for whatever reason, now that I a divorced, I felt like I had my s--t together, Natasha. I felt like I did. But now I feel like I'm in some sort of form of arrested development."

He sighed, adding, "I liked being married."

So today, he is single—and down a friend. At least for now.

"I'm taking a break from Tom right now," Schwartz told Brittany Cartwright and Jax Taylor on the June 7 episode of their podcast "When Reality Hits with Jax and Brittany," "I haven't seen him in a while."

"He made a big mess and he left it for us to clean up back at the businesses," he explained. "It's hard for me not to feel resentful of him."
