I hope you've retained a good attorney
It's hard to comprehend how some crazy-acting alky can get the police to buy her story, but I've heard of it happening before! In fact, my husband called the police on me in late January because I slammed our bedroom door. That's it. I reacted and I generally don't react. But there I stood outside my bedroom door in my p.j.'s trying to explain to the officer what sort of insanity was going on in my alcoholic home.
If you have a good attorney and solid character witnesses, that should be in your favor. This woman has put you through the wringer. Now is the time to perhaps begin to see that regardless of how you two have separated (and it certainly wasn't in a sane or civilized way with her ranting and raving!) that it was meant to be. At least you have the opportunity to be something more than someone's whipping post or scapegoat.
I think it's time to let go of the victim role. You've taken punishment enough.
