"He'll always have some influence on me for the 13 years that I did know him," says Matthew, now 19. "I still want to be a dad like him one day."
Julia, now 13 years old, says she still has her "daddy hug pillow." "It makes me feel good to have it. I feel like I'm just getting a great big hug from him all over again," she says.
Christie says that though she and her children have tried to move forward, she still misses her husband every day. "He would've wanted his kids to be happy, and he would have wanted me to be happy, and so we do what we can to live a new, normal kind of life, as a new, different kind of family," she says.
