susiesutt is on the right track with this.

"I promise- Just hold on a little more-"

These lyrics right here really say what's going on in this song. The songwriter is saying to this person to hold on a little more. It's like a desperate attempt to try to keep her with him. The songwriter is trying desperately to promise the world, knowing that they can't provide it now, and it almost seems as if this person they're singing this to is about to leave. The fact that the words "I promise" are said over and over, it really shows the desperation in this guy's voice.

The melancholy message really stands out in the Aeroplane remix, give it a listen!
