Breaking Benjamin - Hollow Lyrics Meaning

I think This song describes what it's like to be walked out on. You plead with the person, and hope that they come around. I also think that the one who left him was feeling depressed... [find a way to leave The pain behind].

After the breakup, the guy is feeling depressed too... and words are hinted in how he feels about The breakup --> "Hollow"

The title itself expresses that void feeling you have after the love of your life has ended it with you. You're just a shell of who you once were. Nothing is left. You're empty. Going through The motions of living, always missing the one that got away.

Maybe that's just how I interpreted the song.

This person doesn't want to move on.
