Lyric discussion by anewlife 

It seems to me that he's singing about a relationship that is comfortable and established, but doubts or what-ifs keep sneaking to the surface of both of their minds.

He is tempted to wonder if someone else could make him happy, but he cuts off those thoughts and focuses on making her happy instead. After all, she is really the one for him.

But she also has her suspicions. They have been together so long though, that she can't imagine or see how to change things.

I think it's a song about trying to be committed in the face of imperfection or even temporary unhappiness. It leaves me with a sense that they'll stick by each other and that the doubts will pass..

Keep her on your right, Josh!
