I finished the book The Other Significant Others: Reimagining Life with Friendship at the Center by Rhaina Cohen.
While I liked the idea, the book was very heavy on anecdote, and I wanted more discussion about the implications of decentering romance and committing to friendship -- and perhaps more research.
Instead of positing that friend partnership was an option, it seemed, instead, to show, perhaps without meaning to, the ways that society isn't yet ready for types of partnership outside of romantic coupling. If other people aren't judging, the law gets in the way, or one friend-partner may suddenly decide to center romance with someone else.
And while even if you find someone who holds the value of finding partnerships and close found family members, it's even rarer to find people who you harmonize with.
Since we've been inundated with the "romance/marriage at the center" story from birth (looking at you, Disney, etc.), it's really hard to resist the notion and follow another path.
