This song is entirely a bout a girl whom the person was deeply in love with. No doubt that they no longer have this inner emotional love relationship that connects these two people.
*(First verse)*
He introduces the girl he is singing about. They have not met for a very long time. Something has happened, either she has moved on with another guy or she does not want anything with him anymore.
*(I've been saving these last words for one last miracle
But now I'm not sure)*.
He's confused here, left hanging, speechless, and not knowing what to do with the current situation. On the other side, she has her own life and she has moved on.
*(You just get me like I've never been gotten before)*.
This part of the song according to my view is about him feeling so special when he was close and together with her. But he's singing this out of deep dissapointment and heartbreak of not having her anymore.
