"Happy Father’s Day to the best dad in the world," he wrote on Twitter. "I miss you so much. Enjoy your day up in heaven dad. Thank you for watching over me every day, I love you."
"My heart is broken, I lost my best friend and the best man I have ever met last night," Jax tweeted in December. "I love you so much dad I can’t even breathe anymore."
He admitted in February that it hadn't gotten any easier.
"It’s been 2 months since my father was taken from me," he tweeted. "Every day has been such a battle, I try and hide it the best [I] can because that’s what he would want but it has not been easy. I miss you dad so much. . . "
