HGTV Star Jen Hatmaker Reveals How She Discovered Her Husband’s Affair—and How Long It Took Her To Kick Him Out of Their Texas Home

"My Big Family Renovation" star Jen Hatmaker has candidly opened up about the "shocking" way she discovered her now-ex-husband, Brandon Hatmaker, was having an affair—and how long it took her to kick him out of their sprawling Texas home.

The 51-year-old home renovation pro detailed the words that led her to believe her husband of 26 years was cheating on her in her memoir, "Awake," which hits shelves on Sept. 23.

In her upcoming tell-all, Jen, who shares children Gavin, Sydney, Caleb, Ben, and Remy with her ex, chronicled the words she heard her then-spouse utter before he fell asleep, smelling of alcohol.

"I just can’t quit you," her ex whispered into the phone at 2:30 a.m. on July 11, 2020.

Over the next four hours, the HGTV star searched through her husband's computer and found a "trail of betrayal," forcing her to realize that she had reached "the end of my life as I [knew] it."

Although she didn't share many details about what she discovered on her ex's computer, she did reveal that the affair had been going on for a "devastating time span," and he had been showering his mistress with "expensive and lavish gifts," which led their family into "financial chaos."

By the time the sun came up, Jen had kicked her husband out of their Texas abode.

In her explosive memoir, the home expert confessed that the affair marked yet another issue in their crumbling marriage.

She admitted that they had not had sex for two years and had been in marriage counseling.

While speaking to the New York Post, she said, "To some degree, I almost disassociated. It was so outside the realm of what I would have ever considered a possibility for our life, our marriage, our story.

“It was so shocking and stunning, and I almost could not process it. I couldn’t even cry."

In the months that followed, Jen suffered from depression and anxiety while trying to raise their five children during the pandemic.

“I did not know if I was ever going to be happy again,” the home pro said.

Jen, who hails from Kansas, explained that the way she was raised and her religion made the aftermath of their separation even more difficult.

“Inside of that culture, the men are the leaders. They are the pastors. They are the leaders of the family, of the marriage. They are the spiritual authorities. And the women are essentially the support staff," she said.

Jen tied the knot to Brandon when she was 19 years old. They worked at a Baptist youth camp in Oklahoma, where they started their own evangelical Austin New Church in 2008.

In the months before she discovered Brandon's affair, they began going to marriage counseling.

“I thought that we were deeply working to repair. We had kind of reconnected sexually. … And so there, at the very bitter end, I thought that we were trying, but we actually weren’t.

“There were a lot of unaccounted absences, and the phone was never ever, ever, ever out of his hand or sight. All the warning signs were there, but I did not want to face those," she explained.

She noted, "He [told] me clearly that ‘trying requires certain feelings to be there’ and they aren’t anymore and they won’t be coming back.”

Jen—who is now in a long-distance relationship with author Tyler Merritt—revealed that her ex, who got engaged to another woman a year later, made "no reconciliation effort" after she kicked him out of their house.
