The Goop founder appeared on The Drew Barrymore Show, chatting about remaining friends with the Coldplay frontman and how they've navigated raising their children together, after famously 'consciously uncoupling' in 2016.
"It's like you're ending a marriage but you're still in a family. That's how it will be forever," the actress, 47, said.
"Some days it's not as good as it looks. We also have good days and bad days, but I think it's driving towards the same purpose of unity and love and what's best for [our kids]."
Paltrow, who shares Moses, 14, and Apple, 16 with Martin, says she felt "really lucky" that she had a doctor who gave them "a rubric for how to" co-parent successfully, saying it's important to remember that "every relationship is 50/50."
"We all are trying our best," she told Barrymore. "I really wanted my kids to not be traumatised, if it were possible."
"Chris and I committed to putting them first and that's harder than it looks because some days you really don't want to be with the person that you are getting divorced from," the Oscar winner explained. "But if you're committed to having family dinner, then you do it."
Paltrow penned an emotional essay in British Vogue in August, detailing the heartbreaking moment the couple knew their marriage was over after 12 years of marriage
"I found that I was not at a fork in the road. I was well down a path," she wrote.
"Almost without realising it, we had diverged. We'd never find ourselves together in that way again.
