Posted on Facebook in March, her letter said: 'I feel you in my heart and soul so strongly. I am more blessed to have been your wife than anything else in my life. 'Today, I am thinking of our new relationship, when you rented a boutique hotel room in San Diego and surprised me with two dozen long stem pink roses when we arrived. You got us tickets to a local improv type play. I knew then I was the luckiest girl in the world to be with tough, romantic, loving you. 'Today, I have a choice. I can bury myself under the covers and acknowledge the pain of missing you and mourn the future anniversaries without you. Or, I can celebrate never having a day without you in my heart because you loved me enough to leave me a lifetime of memories and beauty. 'I am somewhere in between today. I loved you yesterday, I love you know, and I will love you all the days of my life.' Kyle was considered the deadliest sniper in American history, with his kill count thought to number about 160 confirmed, with many more probable kills.
