Jax Taylor "hit the bottom of the barrel" when Brittany Cartwright was flirting with one of his friends.
The 45-year-old star has admitted to feeling devastated when he learned that Brittany, his estranged wife, was texting with his friend Julian.
Jax - who married Brittany in 2019 - said on the 'Hot Mic' podcast: "We were sitting in my house, and her phone was on the coffee table. And a message popped up, and I looked at it, and it was a simple message from Julian.
"But it was at night, and it was just a very weird message, and I called her on it. I caught her in a couple of lies, and then I got it out of her an hour into the conversation. She finally broke and told me."
Jax felt particularly hurt when he discovered that Brittany, 35 - who filed for a divorce earlier this year - was flirting with one of his friends.
He said: "I don’t think I would have been bothered by it if it was somebody else that I didn’t know. There was a whole five or six months where I wasn’t seeing anybody, but this was going on."
Jax admitted he "went crazy" when he discovered that the duo were sending flirty photos to each other.
He said: "I lost it. That was where I hit the bottom of the barrel. That's where I saw red. I kind of had an out of body experience, I'm not gonna lie to you. I went crazy."
Jax actually wants his estranged wife to find happiness. However, he hopes it's not with one of his own friends.
The reality TV star said: "I want her to meet somebody, just not somebody I know."
