Emma Heming Willis admitted it was difficult to make the decision to live separately from husband Bruce Willis amid his battle with frontotemporal dementia - but ultimately, she felt it was what was best for their kids. In her new book, The Unexpected Journey: Finding Strength, Hope, and Yourself on the Caregiving Path, Heming Willis, 49, revealed how she told her daughters, Mabel, 13, and Evelyn, 11, that Willis, 70, would be moving into a second home. "'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.
