David Whyte argues that friendship helps us “make sense of heartbreak and unrequited love” — two concepts to which he dedicates entire separate word-meditations. He writes of the former:

HEARTBREAK is unpreventable; the natural outcome of caring for people and things over which we have no control…

Heartbreak begins the moment we are asked to let go but cannot, in other words, it colors and inhabits and magnifies each and every day; heartbreak is not a visitation, but a path that human beings follow through even the most average life. Heartbreak is an indication of our sincerity: in a love relationship, in a life’s work, in trying to learn a musical instrument, in the attempt to shape a better more generous self. Heartbreak is the beautifully helpless side of love and affection and is [an] essence and emblem of care… Heartbreak has its own way of inhabiting time and its own beautiful and trying patience in coming and going.
