Book excerpt: Not all friendships are meant to last forever. There can be so much good, so much power, so much love in female friendships. But there is also a dark side of pain and loss. And surrounding that dark side there is often silence. There is shame, the haunting feeling that the loss of a friendship is a reflection of our own worth and capacity to be loved. My Other Ex: Women's True Stories of Losing and Leaving Friends is a step toward breaking that silence. The brave writers in this engrossing, diverse collection of 35 essays tell their own unique stories of failed friendships and remind us of the universality of loss.
