"I don't think he's concerned about breaking up a family," Lewis says.
"We've been getting along pretty well -- until I found out that he went out on a date on Saturday night," Lewis told his listeners on Tuesday's "Jeff Lewis Live." "So that, number one, is a big f--king misstep."
According to the real estate professional, his ex had dinner with a man he also knows at celebrity hot spot Mastro's Steakhouse in Beverly Hills. Lewis believes the restaurant choice was deliberate; he thinks they wanted to be seen.
"I asked him -- he started therapy on Wednesday -- and I asked him, 'Well, what does your therapist think about your date?' And the therapist said that it's good for him to information gather," Lewis said. "What I wonder is if he was honest with the therapist and explained the history with this person, because I know who this person is."
Lewis refused to name names but assured his listeners he had done some "information gathering" of his own.
"I will not say his name, but I think just for today, we're gonna call him Homewrecker," he said, explaining that he believes "Homewrecker" has been in the picture long before Saturday night.
"Homewrecker, I think, has been in his ear for quite some time," Lewis said. "I think Homewrecker has exploited a very vulnerable situation. I think this started as a gym buddy friend, and I think this person has had his sights on him, Gage, for quite some time. I think he was very aware of what was happening."
"I don't think he's concerned about breaking up a family or jeopardizing Gage's career or financial situation," he continued. "I don't think he's concerned about that at all. And I doubt this person's intentions, so we'll just leave it at that."
Lewis was admittedly "in pain" when he first discovered his ex had already moved on, but he used that pain to force himself into "the online dating world."
"Because I was in my bad space on Sunday, I decided, 'Well, maybe it's time to start dating,'" the interior designer said. "So I started dabbling in the online dating world. I met someone who was kind of interesting. We started talking, we exchanged pictures and we started texting fast and furiously. And that went on throughout the day. And we have a lot in common, seems like a busy guy, professional."
Despite the instant chemistry, Lewis said the man wasn't too keen on the fact that he shares 2-year-old daughter Monroe with Edward; therefore, the two never met up.
Last Thursday, the Bravo star announced Edward had moved out of their California home after deciding to go their separate ways the night before.
