I think this song is about someone who has an unrequited love for someone.
In the beginning she says she has to let it go and move on, because they don't like her back.
She sees that he doesn't care about the whole thing but its driving her crazy because she likes him and he doesn't even show any emotion.
She wonders if he might've liked her like she wanted him. And she can't change him, or the way he feels, and he can't change the fact that she likes him.
