There is no such thing as closure. Family therapist Pauline Boss says that the idea of closure in fact leads us astray — it’s a myth we need to put aside, like the idea we’ve accepted that grief has five linear stages and we come out the other side done with it. She coined the term “ambiguous loss,” creating a new field in family therapy and psychology. And she has wisdom for the complicated griefs and losses in all of our lives and in how we best approach the losses of others — including those very much in our public midst right now.
