New York heiress Belle Burden says her ex-husband refused to give her 12-year-old child a bedroom after the divorce.

Belle Burden almost lost everything in a dramatic divorce, but for her, the hardest part was the breakdown of her children.

Burden, a wife who shared the story of her breakup with hedge fund executive Henry Davis in her book, “Strangers: A Memoir of Marriage,” recently appeared on Molly Sims’ podcast, “Lipstick on the Rim,” where she talked about how her three children were affected by her ex-husband’s actions.

The two children were not immediately affected by the divorce — their oldest lived with friends, and their middle child attended boarding school — but their youngest, Burden said, “really wanted a bedroom” in his father’s new house.

“He was sending her links to Pottery Barn in her room,” Burden explained of their daughter, who was 12 at the time.

“And she just insisted that she was done with this phase of her life where she was going to have a baby like that, and homework and dinner and all that kind of stuff.”

As she recounted in her book, Davis told her she wanted a divorce after discovering he was having an affair.

They were married for 20 years.

He eventually moved into a two-bedroom apartment, then turned his spare room into a home office.

“That’s been the hardest part of this, and the most enduring part,” Burden admitted.

When Sims and his co-host, Emese Gormley, expressed disbelief at Davis’ selection, Burden added, “I have to be clear that it’s not a situation where he moved across the country and had a new family. He lives far away from us. He’s always in touch with the kids. He’s very kind and sweet to them. But he was very clear that he wasn’t going to do it that day, and he wasn’t going to do all that in college. It really was like turning off a switch.”

In her book, Burden explained that when their children were young, she devoted all her time and energy to raising them while Davis focused on her work, often joking, “I don’t wash them, I don’t wash them, I don’t do laundry or homework.”

Although he didn’t have to deal with the daily work of being a parent, he paid attention to them, he wrote, took them to special places and trips regularly.

But in one of the conversations they had shortly after she left him, Burden wrote that he told her, “You can get a house and an apartment. You can keep the kids. I don’t want it. I don’t want anything.”

Burden asked her attorney to send Davis a custody agreement, which gave them 50/50 custody, thinking she would “realize her mistake” in not wanting more time with their children at that time. Instead, he wrote, “he returned a document that deprived him of all his time, including holidays, vacations, summer weeks. He also included dinner only on Thursday nights.”

He admitted that he believed he thought he was “sacrificing” himself by not formalizing the agreement and that he argued that their children were old enough to decide for themselves if they wanted to see him.

On big occasions, like when their son was having surgery, he said he showed up, but “on everyday issues, he reacted with anger.”

Sims asked Burden during his podcast if Davis had ever talked to him about what happened and why he was distancing himself so much from her and their children.

“It’s the only thing he ever said in the beginning,” he replied.

“He said, ‘I felt like a switch went off. I felt like a switch went off.’

About a year after they were separated, he said he sent her a message at night asking for answers.

“He said, ‘I wish I had an answer for you, it’s not your fault, something broke in me.’ And that’s pretty much what I got. That’s where my head should rest.”

He said that when he thinks about it, he imagines the burner going off, “but also like he was playing this role of being a husband and a father, and he wanted to play it, and he was stepping in. And then, like a stage actor, he was like, ‘I’m done with this role,’ he took off his costume, left the stage and could do it gracefully.”

Sims asked how the kids are coping with not having Davis in their lives as a real dad, and Burden said, “They’re amazing because they love him, and they’re protective of him, and they’re actually very good now at reaching out to him to do things that are comfortable for him, like going to a hockey game or something.”

She said “they’re very good at navigating that,” but added, “For me as a mom, I think the biggest challenge for me is acknowledging their truth, that ‘this is what’s happening, this is not normal, that you don’t live with your dad’ … that’s not who you are.'”

As for Davis’ reaction to the book’s release, Burden admitted that he heard she was “not happy.”

He first published a summary of his story in the headline of a column in the New York Times, which he had to sign off on – he said that he thought “he doesn’t see anything wrong with this story, like, he’s a man, he’s allowed to go this way.” But now that, as Sims put it, “the whole world, every American woman hates you,” she’s “surprised.”

“He said, ‘I don’t think I did well this time,'” Burden said.
