As they continue to deal with Joey Feek's terminal cancer diagnosis, Joey + Rory have learned firsthand just what the vows they made on their wedding day really mean, and Rory Feek has found himself figuring out how to prepare for life after his wife is gone.

"As Joey has had to learn to come to terms with what is happening to her body and what the future holds, it's been important to her to share some things that she wants me and our girls to remember after she's gone," Rory Feek tells People. "More than once, I have found myself beside her bed taking notes as she shares things like when the best time to plant the garden will be this spring, how to prune the fruit trees and to make sure we still set aside a percentage of what we make as a tithe each month."

Fortunately, the husband and wife have received an outpouring of love and support from family, friends and fans that has helped make this trying time a bit more bearable.

"We are surrounded by Joey's family here in Indiana, and life is a revolving door of sisters, parents and nieces and nephews -- all pouring love and time into Joey and our little family," Feek explains. "Though the situation and conditions that brought us here are very difficult, it has been a really beautiful time for Joey and all of us. Not hardly an hour of the day goes by without someone telling someone else that they love them. It's hard to ask for more than that."

As a couple, the Feeks are remembering their promises to love each other "for better or for worse" and "in sickness and in health" -- and they continue to set a shining example.

"For better or worse aren't just words you say anymore," Rory Feek says. "Because of all Joey is going through, it's given me the opportunity to live them every day, and follow through and mean the words I said to her at the altar."

In late October, Feek informed fans, via his blog, that his wife’s first round of chemotherapy and radiation treatments for Stage IV cervical cancer did not help; rather, two quarter-sized tumors had appeared in the same area that the doctors had been treating, and several more tumors had appeared in her abdomen. In light of that sad news, the Feeks stopped all medical treatments, returned to their Tennessee farm and canceled all of their Farmhouse Concerts that were scheduled for November and December. They have been spending time in Joey Feek’s hometown,visiting with family, friends and other loved ones, and in early November, Rory Feek revealed that his wife had entered home hospice care.

“Her pain and discomfort has continued to increase daily and so has the morphine to help her be comfortable," Feek wrote in early January. "The dosage she’s needed to keep the pain away has quadrupled in the last four days. I’d like to tell you that she’s doing great and is going to beat this thing. But I can’t."

The husband-and-wife duo are set to release a new album, Hymns That Are Important to Us, in February, and Rory Feek says that the project will be not only the last for him and his wife, but his last as an artist as well.

“This is the last record that Joey and I will ever get to make and the last songs we’ll ever get to sing together,” Feek says. “I have no desire to go on singing or performing without her.”

Proceeds from Hymns That Are Important to Us will benefit the Loeys-Dietz Syndrome Foundation, in honor of the Feeks’ daughter Indiana‘s best friend Scout, who has Loeys-Dietz syndrome. The charity was selected by Joey Feek.
