The way I look at it, you really don't know WHAT she will do when you tell her you've had enough of having a sword hanging over her head. You have not delivered that speech or followed through on it before or yet so you don't know what she will do. But you have to mean it when you say it, b/c she'll test it and doubt it and swat at your resolve b/c she's seen you waiver before. Not this time. This time is different and she needs to FEEL THE IMPACT of how different this moment in time is.
