There is so much emotion and hurt in this poem. I feel saddened by the words shown as it tells a story.
I see it as a loving couple who obviously used to think the world of each other - their relationship slowly breaking down. One side more aware of the nothing that the relationship has become and the feelings that they have lost (or at least one person as lost)
It reminds me of the words I love you and how people say it for the sake of saying it without meaning it. When a relationship hits rocks bottom and they go through their lives trotting along without trying to build the relationship further.
I keep seeing one person more in love than the other.
