I always took this as - after the events in the "title track" the male protagonist has become emotionally invested in the object of his affections. She on the other hands treated it as a casual fling; and is involved with someone else "I thought you knew".
Interesting reversal on the "guys are the ones that have meaningless flings and women don't".
Lots of drama between the two parties subsequent to their involvement.
