Lyric discussion by cambridge22 

Very sophisticated and ironical song. It is about a woman who is playing with him, who did not have a real relationship with him but went through a series of set scenes. At least partly such people play for the effect on those around them - hence the ironic "not a dry eye in the house" - taking her viewpoint and the effect she wants to create.

"It was almost like a movie - the way you said goodbye You must have spent a lot of time rehearsing each and every line"

The song is not a metaphor as suggested above, but the realisation that his lover was an actress. It is interesting that the song was written by a woman.

Of course there might be a deeper irony intended too, a sort of meta-irony, since of course singers are actors playing with our emotions...
