The song is obviously dedicated to Jessica!
Justin is describing how he sees Jessica and the new life he's about to start with her : "I'm looking right at the other half of me" "That we're making two reflections into one", "And now it's clear as this promise" (they made at the chruch) "So now I say goodbye to the old me, it's already gone. And I can't wait wait wait wait wait to get you home"
This is the best feeling ever, to find a person who is just your reflection, your other half walking in front of you :)
