I think this song is about how we can sometimes savor emotional pain. Like when we discuss our deepest secrets and feelings or even when a friend dies, there is somthing 'sweet' in that depth of emotion. It is dangerous, like catching bullets in your teeth, and you can even go so far as inflicting pain on yourself to get at your innermost emotions, but there is light in all that darkness that's inside you and we want to get at it, sometimes at any cost. "We're happy, and then again we're not." There is a touch of irony in the song, like the singer isn't sure that they are right in enjoying the pain, so he is trying to justify it. I don't really get the part about 'and now we don't remember'. Maybe just that we don't remember how badly we can hurt, so we do it all over again.
