"Carved in your name with my poker knife" It could be just a metaphor of the extremely need of trying to keep her inside. "Feels like there's something broken inside" "And you wonder when you wake up, will it be alright" Maybe things are not going alright but it doesn't mean he doesn't want to be with her no matter what. "All I know is that I love you so". He really loves her.
