This song is about your ex, and no matter how hard you try to tell them you love them and you care about them and you need to be with them it doesn't matter because they could honestly care less about you, and what happens to you. This song reminds me of my ex because I felt that after he left, there is a big hole in my heart that can never be filled, and no matter how hard I try he will never come back and I have no choice but to move on no matter how much it hurts me inside.
