Anna Faris has kept relatively quiet about her split from Chris Pratt, despite a flurry of rumors about what exactly lead to the dissolution of one of Hollywood’s most enviable marriages. That might change when her new book, Unqualified, hits shelves next month. Though the book was written before she and Pratt announced their split (the Guardians of the Galaxy star wrote the book’s forward), it’s being billed as an intimate tell-all that’s “part memoir, part humorous, unflinching advice” on relationships and “finding love.”

In other words, tea will be spilled. While Faris may not get into the guts of what ended her marriage to Pratt, she does reflect on the nature of their relationship. Take for instance, her most recent column in Cosmopolitan, which is a version of a passage that appears in her book. In it, Faris writes that she only recently discovered the value of female friendship.

“In my 20s, I thought it was cool to say I was a guys’ girl. I didn’t realize until later how lame I sounded, bragging as though having a lot of girlfriends was a bad thing,” she says. “Back then, I thought that having the approval of my stoner guy friends was of greater value than having the approval of beautiful blonde sorority girls, so I touted my male friends as if my association with them spoke to how cool I really was. I was selling my own gender down the river, and I wasn’t even getting any fulfillment from the relationships with those dudes.”

Faris goes on to discuss how she never bought into the idea that a person’s partner should also be their best friend, something that was especially true when it came to her marriage to Pratt. “I was once told that I didn’t need a tight group of girlfriends because Chris should be my best friend,” she writes. “But I never bought that. The idea of your mate being your best friend—that’s overhyped. I really believe that your partner serves one purpose and each friend serves another.”

While that separation of friendship and romantic relationship was something that may (or may not) have worked for Faris and Pratt, it’s not a rule that should be etched in stone.

The reason that kind of closeness is usually viewed positively is because it implies a intimacy and a trust that’s rare. Think about it: Is there anyone on this planet you feel more comfortable around than your best friend? If you can be your authentic self around the person you’ve sworn to spend the rest of your life with, isn’t that something that should be cherished instead of rejected?

Faris doesn’t elaborate what “purpose” she thinks a partner is supposed to serve, or if it was that thinking that led to her split from Pratt. We’ll have to by her book to find out.

Unqualified is available on October 24.
