'Summer House' Reunion Sneak Peek: Carl Radke Admits to Being Scared of Lindsay Hubbard

'Summer House's Carl Radke split from his ex-fiancée, Lindsay Hubbard, last year, just months before their wedding.

It's a battle of the exes in the upcoming Summer House reunion. The dramatic two-part reunion kicks off on Thursday, June 6, as Andy Cohen sits down with Amanda Batula, Kyle Cooke, Paige DeSorbo, Lindsay Hubbard, Ciara Miller, Danielle Olivera, Gabby Prescod, Carl Radke, Jesse Solomon and West Wilson to revisit a season of blossoming friendships and heartbreaking relationships.  

In a sneak peek for the reunion of season 8, which Bravo boasts is the series' most-watched in franchise history, former fiances Radke, 39, and Hubbard, 37, go head-to-head on the abrupt end of their engagement last August and the tumultuous aftermath.

"I did not walk out of that apartment that day wanting to end the relationship," Radke says as a few cast members, including Hubbard, look on in disbelief. "I'd hoped maybe it would've gone differently."

Hubbard then claims that Radke told her he "had to have the cameras there."

"You have the apartment, I paid half the rent for nine months," Radke claims, to which Hubbard hits back, saying, "You want a pat on the back for that?"

Season 8 of Summer House documents the journey to the altar for the reality stars; but there wasn't a fairy-tale ending for the two. Days after filming wrapped last August, cameras went back up to capture a conversation between Radke and Hubbard, during which Radke called off their wedding

"Carl Radke and Lindsay Hubbard have called off their engagement. The two were set to get married in November, but Carl told Lindsay he couldn't move forward with the wedding. The breakup was filmed and will most likely play out on the next season of Summer House," multiple sources told ET.

The former couple has been part of Bravo's reality series Summer House since its debut in 2017, and were initially just friends. However, they took their relationship to the next level in October 2021, officially confirming their romance to the world in January 2022. In June 2022, the couple confirmed to ET that they were moving in with each other and were "excited" to take that next step.

Speaking to ET in November at BravoCon in Las Vegas, Radke said the heartbreaking decision was a byproduct of analyzing a relationship that, to him, had serious foundational issues he just couldn't look past.

"I wanted to get married and have a family, but I think when you are getting to a point in your relationship where... we've been in couples therapy since November of 2022 every week for foundational things that we needed to work on," Radke told ET. "We've really been committed to try and work through things and get on the same page, but a wedding, having a family -- that is a serious, serious thing. And I think -- given where the summer was and how our relationship had been going -- people will see that I had to really dig deep inside and have a very difficult and emotional conversation with her that I felt that I had to do because I really believe our relationship wasn't in that position where it needed to be."

Nevertheless, a source told ET in September that Hubbard was "blindsided" and "completely devastated" by the breakup, and that she was leaning on her female co-stars to get her through the split.

"I sat down on my couch looking to repair a conflict about careers and future finances," Hubbard told ET in February of what she thought she was filming that day. "I was like, 'OK, we have to get on the same page.' Like, we had this conflict the other day about what we're doing in life and how we're making money, and that's what I sat down thinking that we were repairing, the conflict. And he sat down with a very different vibe." 

Hubbard called the split "one of the most traumatic situations of my entire adulthood," maintaining that Radke blindsided her.

The reality star was quick to shut down speculation any of this was scripted or staged, firing back at critics who question the timing of it as convenient. Hubbard's breakup came in the wake of sister show Vanderpump Rules' "Scandoval," the highly publicized split of castmates Ariana Madix and Tom Sandoval due to Tom's cheating with co-star Rachel (née Raquel) Leviss. Other Bravo shows, including Southern Charm and The Real Housewives of Beverly Hills, also featured surprise scandals and splits in the months after Scandoval, adding fuel to the fire that the network was somehow generating manufactured drama.

"I wish that could've been the case," Hubbard laughed. "I think people sometimes forget that I'm not just a character on a TV show. I'm a human, and this is my real life."

During an appearance on Watch What Happens Live with Andy Cohen earlier this month, Radke said he made "the right decision" to end his relationship with Hubbard. 

"I think it's better. It seems like she's happy and moving along. I wish her all the best. I hope he treats her well and she's happy. That's all I can ask for," he told Cohen.

Earlier in the episode, Radke admitted that he "absolutely" should've been more upfront about his needs in the relationship.

"I'm seeing myself eight, nine months removed in kind of a different way. There's some things I wish I was a little more firm [on] or really just made sure she knew I was serious about," he said. "I have a tendency sometimes to back down from difficult conversations. I think you're seeing some of that play out."

As for why he didn't speak up, Radke said, "I was afraid of hurting her. I'm a people pleaser, which is something that I work on in my therapy and I talk about. With her, I didn't want to hurt her by delivering difficult information even though I just needed to be more upfront with her."

"We had had the safety of couples' therapy where we did talk about a lot of these different topics," he added, "but outside of couples' therapy were a lot of the ruptures, obviously, that happened."

As for the biggest regret he has about how the split played out, Radke reiterated, "I think I could've been a lot more direct with her about how I was feeling at times."

"I think I was dead-set on really just trying to get married. I wanted to get married. I wanted to have a family, but I think we were speeding really quickly down the track," he said. "... I wanted to get married. We were fighting the last two weeks. I think people will watch over these next few episodes some of the other things that come about."

Part one of Summer House's season 8 reunion kicks off on Thursday, June 6, at 9 p.m. ET/PT on Bravo and streams next day on Peacock.
