I'm reading a book called Radical Acceptance. While this book would be filed in the self-help section, it finally penetrated my brain that this title of the book is NOT Radical *Self* Acceptance. It's about accepting everything, including other people, not just about accepting my own flaws.
In the spirit of acceptance, I'll link this NYT article about not getting divorced, that was reprinted in The Week. (I think this woman was also studying the concept of radical acceptance at the time she chose to roll this way.)
Even if we might not chose to handle our own potential divorces this way, it does sound like a tranquil way to deal w. other people's divorces.
