Well needless to say you f'd up pretty badly. Never ever lose your temper. Did you honestly read DB? Demanding an ultimatum ... writing out your feelings and demanding she read them, etc. All total bad moves.
If the roles were reversed and she did that to you, would you want to be married to her?
You have to learn control.
Go and give her a heartfelt apology. Tell her that she doesn't need to accept it, but you want to say how sorry you were for freaking out.

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