There are 3.7 million widowers in America today and three times as many — 11.5 million — widows. Altogether, that’s more than 6 percent of the entire population, and those numbers will increase dramatically as the Baby Boomers take their leave. Although everyone deals with this loss in different ways, there is one common experience that is shared by all. It comes after the funeral, after all the family and friends have left, after the surviving spouse comes home and, for the first time, opens the door by himself.
