I think this song is about forgiveness. In my mind it's about a guy who's girlfriend or whatever cheated on him or betrayed him in some way. Instead of getting angry or breaking up with her, he feigns amnesia, or pretends he doesn't know what she did. It tears him up inside, and he wishes it didn't happen, but he pretends it actually didn't happen for the sake of the relationship.
