Having been through my share of bad relationships, my attention was initially grabbed by the title. My morbid curiosity hoping to find any kind of camaraderie in the tales of some heinous man who commits truly unspeakable acts of betrayal against his wife.  & I did find those stories but ultimately, this is a story about grief.  Mortifyingly honest grief.  I wasn't expecting it and probably would not have picked it up had I known, but I really enjoyed this book.  I feel I gained both life perspective and a broadened empathy for those who've experienced this intimate of a loss.  Memoirs aren't normally my thing but this one was worth it.
