i always saw it as the progression of a relationship as compared to the day, a bit like the sphinx riddle, where it compares a life to the day.
in the dawn of the relationship, it's all pure love and it's easy. in the afternoon, it becomes difficult, and it 'dawns' on her that she's tired of it. in the night, at the end of it all, she sees that they are no longer right for each other.
