"One night recently, alone in bed, I read “A Grief Observed” by C.­S. Lewis, and I came across the observation that “bereavement is not the truncation of married love but one of its regular phases.” He writes that “what we want is to live our marriage well and faithfully through that phase, too.” Yes, I breathed. Bereavement is more than learning to separate from a spouse. Though I can no longer comfort Paul, the other vows I made on our wedding day — to love Paul, to honor and keep him — stretch well beyond death. The commitment and loyalty, my desire to do right by him, especially as I raise our daughter, will never end".
