What are some songs about still liking someone who has lost interest in you?

So, I kind of like someone and not too long ago, he seemed to like me
too. But recently, that feeling has mysteriously gone away. And I
think it may be because he lost interest. I'm just curious if there is
any song that relates to the way I'm feeling. I would prefer the music
to be in the style of alternative rock. (e.g. Mayday Parade, All Time
Low, Lifehouse etc.)
