The way I interpret it is that this song and the video is something of a recreation of "The Little Mermaid" not the soft Disney version but of the first versions.

In the story, the little mermaid looks up to the world above her and falls in love with the prince. She eventually gets the sea witch to cast a spell on her to turn her human and walk on land to be with the prince. She is supposed to get the prince to fall in love with her, or else she will die. The prince never does and leaves her for someone else, and then the mermaid dies turning into sea foam.

In the music video, when the girl was walking out of the rink, she was dripping water, perhaps proving she has just had the spell cast on her. The ice rink may represent the land the prince lives in. While the two dance for a while and share an intimate moment, he eventually leaves her. She starts to turn into foam even when she was dancing with the prince, but it pours out after he leaves her.

The moral of that story is not to sacrifice everything you have for one person who may not even like you back.

Or, don't become some one you are not for someone else or else it will be the death of you. And especially not for "love."
