I think the song is about a divorced couple who are reflecting back on their time when they were together. The songs title and chorus show how the couples' kids are missing the feeling of both their parents being together. One of the parents who doesn't spend a lot of time with their kids, thinks their children are fine while the other parent who spends more time with the kids, knows this isn't true. The rest of the song besides the chorus is the couple remembering their time together.
