Tom Sandoval Has Heated Spat With Lisa Vanderpump Over Life Post-Affair

Tom Sandoval's meet-up with Lisa Vanderpump descended into chaos on Tuesday's installment of "Vanderpump Rules" ... with her post-affair grilling not sitting well with him.

Remember, Tom was busted for cheating on Ariana Madix with Rachel Leviss in March 2023 ... with cameras rolling on the new season a few months later -- and by the looks of it, at the time of filming, he was still in the thick of it all.

Tempers flared as Lisa quizzed Tom on why he was still living with ex Ariana in their shared home ... urging him to do the gentlemanly thing of moving out, giving her space, and selling the pad. Tom wasn't having any of it, saying he wanted Ariana to let him buy her out instead, adding, "One of us can keep it because it is a great house. I put a lot of work and money into it."

There was clearly no changing his mind ... telling LVP he'd already sent AM a letter of intent and his real estate agent had also spoken to her about it ... but so far, there'd been radio silence from her.

Tom became more wound up when Lisa asked him if he was doing his best to move on from the scandal he'd created in the first ... raising his voice to get his point across that he knew he was responsible for the mess but was doing his best to navigate it.

Though, Lisa clearly didn't like his tone, urging him to stop, have some remorse, and stop being angry ... but he said his fury was warranted 'cause she was attacking him. Yikes.

As for where Tom stood with his VPR costars ... looks like things weren't great on that front either. He blasted them all for their mob mentality .. telling Lisa whenever he apologized, it fell on deaf ears ... and when he cried, they accused him of shedding crocodile tears.

He urged her to see things from his POV, saying he's not exactly living a rockstar lifestyle, ... adding he's battled with suicidal thoughts over the aftermath of the affair.
