Andy Spade maintained that he and his wife decided to take time out and live in separate places for 10 months. But the two vowed to continue raising their daughter together, so they often ate dinner together and took vacations as a family, Andy Spade added.
“We were best friends trying to solve our problems the best way we knew how,” he recounted. “We were together for 35 years. We loved each other so much and we just needed some time.”
Kate Spade had no alcohol or substance abuse problems, he added.
Andy Space referred to her wife as the kindest person he had ever met and explained that he could not understand her life without her.
