Don't file unless your done. Don't believe you're done unless you've detached. And I don't think you've detached. you're still very angry.
If she filed or didn't file, so what? It doesn't change anything. You continue to get up at the same time. Get your own breakfast. Go to work, etc. in other words, life is the exact same.
So let's say you file today. Is tomorrow any different. not really. not in the way you carry out your day. However, it has disrupted your serenity. you want to hold on to your serenity for as long as you can.
take care
