When talking to Country Music Is Love last November (2013), around the time the track was released, she explained;

"It was when I was going through this time in my life where my now fiancée, we were kind of in a transition stage. I had just moved to Nashville full-time and I was focusing on being a mom and focusing on my work."

Jamie continued, "I was having the struggle of how could I want more? He's a great guy, but I was really was just not in a place to be in that relationship. It's funny, if you fast forward to where I am now and I'm going to marry this man and the song really came full circle."

"It's an older song, but it still means so much to me," she concluded. "It was written at a very vulnerable time. Every time I sing it, it just brings all that back up." Congratulations to the newlyweds.
