It's over for Lindsay Hubbard and Stephen Traversie.

The Summer House star and Traversie have called it quits after nearly a year and a half of dating, a source tells PEOPLE.

A rep for Hubbard did not immediately respond to PEOPLE's request for comment, and PEOPLE is out to Traversie for comment.

The former couple began dating in summer 2019 during season 4 of the hit Bravo show.

Traversie, the Senior Director of Marketing at Tao Group Hospitality, made an appearance in the Summer House season 5 trailer, where the two appeared to start off the summer going strong.

"I really do love you," said Traversie, as Hubbard said she was ready for "engagement, marriage, babies."

But things quickly took a turn, with Hubbard, 33, storming off during dinner and Traversie declaring that he was going to "leave the house."

While it's unclear if he stayed for the duration of the summer, Hubbard last shared a photo with Traversie in September.

"FALLing," she captioned a photo of the couple with their arms wrapped around one another.

The following month, Traversie featured Hubbard in a sponsored Instagram post.

The split comes just months after Hubbard's Summer House costar Paige DeSorbo announced her own breakup from boyfriend Perry Rahbar.

"My boyfriend and I broke up," she said in October on the Giggly Squad podcast, which she co-hosts with her Summer House costar Hannah Berner. "Confirmed, I'm a single girl about the town now."

Summer House season 5 premieres Thursday, Feb. 4 at 9 p.m. ET on Bravo.
