You should have just discussed it with your L like you said you would and then told her such. The way you phrased everything does sound very controlling.
You're still trying to steer her the way you want to and it's not working. Yes she's using your SD as leverage, but go back and look at what you did. It seemed like you were using the paperwork as leverage too.
Standing your ground is one thing. But telling her that she has to go back to talking about the R with you is another. That's the number one no-no of DB.
You're killing your chances.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
