Just like everyone else, I've been there too. Make this the last time dude. Most likely W will see that you were somewhat justified in your outburst, and she'll put off filing. But as you know when you smack her in the face with facts that prove her guilt, it gets you nowhere closer to reconciliation. One of these times she'll be convinced that you can never change, and then you're screwed.
Strive to be like MF. Take W's load of crap, maintain that PMA, show understanding, and come from a loving place. Figure out what kind of jedi mind game you need to perform on yourself to get you past the anger.
When you figure it out let me know. If I figure it out, I will share with everyone here.
