Rory Feek is still mourning the heartbreaking loss of his beloved wife, Joey Feek, a year later.
The 51-year-old country singer recently opened up toSimple Grace magazine for their April issue, and says that while he has no regrets over his time spent with Joey -- who died in March 2016 after a battle with cervical and colorectal cancer -- he would have tried to do "more."
"[I'd] cherish every moment of every day more," he tells the magazine. "I'd love Joey more and serve her more and do a million gazillion things to show her more how much she means to me. No matter how much of that I did, it still wasn't enough. She always deserved more."

Rory says watching Joey's battle with cancer had a profound effect on him, and also brought him closer to his faith.
"You can't watch the woman you love go through what Joey went through and not be changed," he says. "Changed by her. Changed by God. Changed by her faith and how she lived it out to the end of the line. Joey helped me fully realize the potential of my character... and my walk with God."
"There's something powerful about believing He has a bigger plan for us all," he adds.
Rory says that true love never leaves, and is thankful for the time he had with Joey, and for the time he still has with their daughter, 3-year-old Indiana.
"I've been sustained by the love I've been given," he explains. "Love that I know I don't deserve. And I am sustained by God's gift of having time, precious time, to be together, to love our baby, to say goodbye a hundred times. And kiss goodbye a thousand."
