I thnk that he and his gf broke apart and he split with her but hes still hrtin rilly bad inside sooo he can't talk to her and he can't hear her voice atall so she can't call him or anethng and he dumped her because she cheted on him.
You know that its over when the burnin and the yearnin inside your heart aint there anymore and you know that its through when she don't do to you and move you like the way she moved you before and you want to pull her close but your heart has froze you kiss her but her eyes don't close then she goes out of your heart forever and it hurts you but you know that its better.
That really tells the message of the song. Well, bi4now.
