Proof Lindsay Hubbard and Carl Radke's Relationship Was More Toxic Than Summer House Fans Thought

It's probably a very good thing that Carl Radke and Lindsay Hubbard never made it down the aisle.

That's because, in a teaser for part two of Summer House's season eight reunion, the exes both make shocking revelations about just how toxic their relationship was prior to Carl calling off their engagement last August.

In the June 6 preview, host Andy Cohen asked Lindsay about her previous comments that she would regularly take videos of her former fiancé during their explosive arguments, which were a major storyline during the current season. 

"Did you record him other times?" the Watch What Happens Live host questioned, to which she confirmed by replying, "Out of safety."

But the volatility between the Bravo costars was even darker than fans might have realized.

"I've locked myself in bathrooms a couple of times," the publicist admitted, to which Carl echoed, "I've locked myself in the guest bedroom."

Andy, understandably shocked, chimed in, "You wanted to marry each other?!"

Ultimately, they didn't, with Carl standing behind his decision to break up with the 37-year-old on camera during the season eight finale.

"I really believe that conversation was really a micro-chasm of some of the challenges we had in our relationship," he admitted of their explosive final talk as a couple. "The communication and some of those things. It's hard to re-watch, but like I said, I think it's important to watch it and try to move on and heal from it."

However, Lindsay still questioned Carl's motives in having camera crews around for their breakup.

"I walked straight into his room, the second bedroom," she recounted, "I said, 'Hi, do you know why they want to film with us today?' And for 45 minutes straight Carl popped off on me and was screaming at the top of his lungs."

Carl denied yelling at his ex and once again accused her of gaslighting him.

"You can't treat people like that, Lindsay," the 39-year-old fired back. "It's not accurate. You need to own your behavior."

Exactly two weeks after the split news came to light, Lindsay broke her silence and revealed she's "heartbroken" and humiliated" with how Carl ended things.

"My trust has been betrayed, and coming to terms with that has been difficult for me," she wrote on Instagram Sept. 14. "This was not my decision, and I do not agree with quitting a relationship (at this level) without trying everything possible first. I have spent the last couple of weeks finding my own closure and peace. I am forever grateful to my best friends who have not left my side, and have been picking up the pieces of my heart and life every day from the fallout."
