Things have seemingly taken a turn for the worse since, as Jeff explained the emotional toll continuing their professional relationship has taken on him on Tuesday’s show. “By working with him, it was my version of still seeing him, still spending time with him,” he said. “Now that he’s leaving the business, it’s like breaking up again. It’s a second break up.”

He also admits, it was likely a misstep to continue working together post-split. “It was not a healthy choice,” he said.

The pair separated in January after ten years together. They share a daughter, Monroe, 2.

On the same episode, the famous house flipper noted that the “open-door” co-parenting arrangement they had agreed upon is “not working out.”

“I don’t necessarily want to be there when he’s there all the time. I said, ‘You’re not coming over twice a day anymore. That’s just not realistic.’” Instead, he says he hopes they can plan who will care for Monroe when each Sunday for the week ahead as both have irregular schedules.

Despite the shift, Lewis said he doesn’t think they need a formal custody arrangement or any legal action. “Right now it’s good,” he said. “We’re having a conversation. I don’t think we need attorneys at this point. He understands now that we do need some structure. We’re probably going to get there.”

Tensions between the estranged couplehave been on the rise of late, however.

Lewis says he reached out to Edward following the unfriendly interaction, but didn’t receive a reply: “I sent him a text and said, ‘Is everything okay? You seemed really, really upset.’ And of course, no response. That’s familiar! So I don’t want to deal with that s–t anymore.”

He also alluded to a new love interest of Edward’s that Lewis has previously called a “homewrecker” who Edward met at his gym. “Let the new boyfriend deal with the f–king mood swings, because I am done. I am retired from the new mood swings,” he said.

Despite the issues they’re facing, a source tells PEOPLE, they’re both dedicated to successfully coparenting. “Monroe’s happiness is Jeff and Gage’s top priority; She’s their world,” the insider said. “They’ve always kept any of the trouble that was going on between them away from her, making it a point not to argue in front of her or around her. She’s totally unaware of any tension. They’re great parents.”
