Bruce Willis’ wife, Emma Heming, recalls delicately explaining to their two young daughters why the ailing actor had to move into a separate home amid his debilitating dementia battle.

“‘We’ve come to a point in Daddy’s disease where the care he requires is changing. It has to be more tailored to his every need,’ I told them,” she writes in her new book, “The Unexpected Journey: Finding Strength, Hope, and Yourself on the Caregiving Path,” according to TooFab.

The mom of two — who shares Mabel, 13, and Evelyn, 11, with Willis — says she also told the girls why having the “Armageddon” star in his own space would be advantageous for them, too.

“Daddy would want you to have playdates, sleepovers, and more freedom than you’ve been able to have here. That would make him so happy,” she added.

Heming, 49, reassured her daughters that they would always be welcome in their father’s place and they could “keep personal things like toys, arts and crafts supplies, bathing suits, pjs, and games” there, as well as “stay with him anytime they wanted.”

The author writes that Mabel and Evelyn “understood” that the decision was for Willis’ “overall well-being and safety” but the entire ordeal was still “a painful time” for them all.

“In fact, it’s still painful for me,” she further admits. “After all, this is my husband, and having him in another home was not part of the future we’d mapped out together. You really can’t dream this stuff up.”

Heming first revealed that Willis, 70, would be living separately from her in an interview with ABC News that aired last month.

“He would want them to be in a home that was more tailored to their needs, not his needs,” she told journalist Diane Sawyer at the time.

However, Heming — who has been married to Willis since 2009 — was met with backlash after the segment aired, forcing her to clap back, “The opinions are so loud and they’re so noisy.

“But if they don’t have the experience of this, they don’t get a say. And they definitely don’t get a vote … And that is what caregivers are up against. Judgement from others and criticism from others.”

In 2022, Willis’ family announced the “Die Hard” star would be stepping away from acting after he was diagnosed with aphasia.

Doctors then discovered he actually has frontotemporal dementia, which affects a person’s speech, personality and behavior, and is a disease that has no cure.

Heming recently shared her husband is losing his speech, but the family has “a way of communicating with him, which is just a different way.”
