We talk to Rhaina Cohen, author of The Other Significant Others, about the importance of "platonic life partners" - friends that you love with a depth and domesticity that mirrors romantic partnership. She tells us how she and her husband structured their life to include communal living with other couples, and her advice to anyone considering marriage: to stop worrying about convention, and figure out what you actually want together. At the end of the episode, Maxson and Emily try to figure out what actually makes the two of them more than just really, really good friends?
