He wrote this song for the one and she has somehow not taken it seriously. Maybe because he never expressed this about her or maybe he hurt her and she feels it is no longer truth.

He wants her to feel what he feels so he wants her to express her feeling so he can write something so touching it will feel special to only her through him.
