Molly Roden Winter and her husband, Stewart, have been married for 24 years. But since 2008, by mutual agreement, they have also dated other people — an arrangement that Winter details in her new memoir, “More: A Memoir of Open Marriage.”

In this week’s episode, The Times’s Sarah Lyall chats with Winter about her book, her marriage and why she decided to go public.

“I didn’t see any representations of either people who were still successfully married after having opened it up or people who were honest about how hard it was,” Winter says. “The stories that were coming out were either, ‘Oh, we tried it. It didn’t work,’ or ‘We’re born polyamorous and it’s just the best and I just feel love pouring out of me 24/7.’ Neither of those things was true for me. I felt like I had learned something really profound through this journey of opening my marriage, and I wanted to share it."
