I think the whole song is a metaphor for the end of a relationship and the hope of it actually getting better again.
The protagonist and his partner had a bad argument in the first verse and stopped talking to each other but he has the hope his/her partner starts the conversation again. The "last dance" is a metaphor for "trying to save the relationship" once again but the protagonist is not willing to start it (again), which is the meaning of the "In the morning I'll be gone
But not because I didn't want to"-line.
