For Taya Kyle — widow of legendary Navy SEAL sharpshooter Chris Kyle — living without her husband is something she hasn’t fully learned to do over these last three years.

Chris Kyle and his friend Chad Littlefield were killed Feb. 2, 2013, at a Texas shooting range — an act Taya Kyle called “pure evil at work.” A year ago, a jury found Eddie Ray Routh guilty of capital murder in their deaths and was sentenced to life in prison without the possibility of parole.

And in an emotional tribute to Chris on the third anniversary of his death, Taya shared with Facebook friends that while her grief “continues to have a life of its own,” she’s choosing to focus on the things she’s learned as she summons the “courage to accept it, feel it and keep moving through it.”

The very first thing Taya said she’s learned is that “some loves will last forever.”
