My friend played this song for me when I was going through a hard time in my life where a guy I liked a lot told me he wasn't ready to move forward in our relationship. Even though I was heartbroken, this song helped.
This song is about someone who is so caught up, not only in a hectic lifestyle, but a relationship which is moving to fast for the place both people are at in their lives. It tells the person to slow down and think about where they are going and what they are doing in their life--to enjoy life for awhile. "don't let love pass me by" refers to the relationship. By this she means to slow down and realize if its meant to be it will happen, but don't ruin your chances by trying to rush into it at the wrong time.
