Jeff Lewisdoesn’t know if he’ll ever reconcile withJenni Pulosafter their recent falling out, but that doesn’t mean that he’s not missing her in his life.

TheFlipping Outstar, 48, was onWatch What Happens Live with Andy Cohenon Monday night and spoke out about Pulos.

PEOPLE broke the news on Sept. 6 thatPulos and Lewis had ended their nearly 20-year personal and professional relationshipafter an explosive fight that will appear in the latest season.

Lewisconfirmed the split and incidenton his SiriusXM radio show,Jeff LewisLive, the following day — revealing that Pulos had madeclaims of “abuse and victimization”and wrongful termination against him after they parted ways to Bravo, and the show’s production company, Authentic Entertainment (Pulos, Bravo and Authentic Entertainment have not commented).

Those claims, Lewis said onWWHL, make it hard for him to see a path back to their friendship. “I’m a very forgiving guy, and never say never, but when someone reports you for abuse to your bosses, it’s kind of something that’s hard to get over,” he said.

Still, Lewis feels nostalgic. “I’ve been watching the show and I already miss her, I will tell you that,” he said. “I already miss her. But when somebody crosses the line, it’s kind of hard to get over.”

While previously talking about Pulos’ claims onJeff LewisLive,he said that the situation convinced himFlipping Outwill be canceled.

“Her making this claim, it put my entire career in jeopardy. My family, my livelihood, everything,” Lewis said. “I just lost my job. I’m pretty sure of that. … I’m pretty sure they’re not going to keep picking upFlipping Outif she’s not on the show. And she’s not on the show.”

“I did it because I thought it really was the best for both of us,” he said, recounting a meeting they allegedly had where they discussed Pulos still appearing onFlipping Outas a friend. “All of this was very civil, I thought. … This fight, I never thought in a million years that would ever break us up.”

But it did. Prior to their meeting, Pulos had apparently made an initial set of complaints to Bravo Authentic Entertainment. And though Lewis claimed that he was cleared after a lengthy investigation, he alleged that Pulos “doubled down” recently and reported him for “wrongfully terminating her off her own show” as well as making “allegations of a hostile working environment.”

“I would never do that to a friend of 15, 16 years,” Lewis said onJeff LewisLive. “I would never put someone – I love her family, I love her kids, she’s a godmother to my child, I would never do that to her.”

Flipping Outpremiered on Bravo in July 2007, and kicked off its eleventh season on Sept. 11. Both Lewis and Pulos are executive producers.

According to multiple sources, Pulos and Lewis haven’t spoken in months. “It’s sad,” one source said. “They used to be inseparable but their differences just got too big to overcome.”

“They found fame together so there was always this thought that nothing could tear them apart, but that hasn’t been the case,” the source added. “They’ll never come back from this. It’s over.”
