After watching the music video, I decided it's about the protagonist having a crisis about his or her marriage. They've been together for a long time now, and they no longer have as much fun together as they used to. He/she feels as if they're drifting apart, much to his/her vexation; Or rather, the protagonist wishes they hadn't grown up so fast, and could relive their days of young-love.
In the video, the guy remains the same age throughout. His wife seems to switch back and forth between herself and her younger-self (either flashbacks or simply in the guy's mind/fantasy). He misses the fun-loving nature of her younger self. The song represents his plea for her to step back and remember when things weren't always so serious, and bring back a little newly-wed fun to their seasoned marriage.
