I would have to agree that it does speak of a relationship, but I find it's more of like a long lost memory relationship;
The man in question in the song (or woman, whichever you prefer) is just starting his life, having nearing the end of some of his goals and he starts to think back on different times in his life when he had choices to make, friends to keep, friends to lose, loves gained and lost, and it all literally overwhelms him in one blow and he thinks to himself "What if it was all different... what if this changed, what if this happens, what would it be like?" He is literally (in my opinion) asking himself the general question of "What if..."
It's a beautiful song because he's reached the stage every person in life goes through; a point in your life where you consider every angle and option and think "What if this changed, what if this happened?" you literally wonder what if it was different and where would you go.
