Should I ruin her or just let it go

Today after being apart almost 2 years I received a petition for divorce from my second wife. Looking back I should never have been with her as we were just a bad mix and she was particularly manipulative, which I didn't realise until near the end.
She makes out she's a god loving woman but in this petition she is trying to ruin my name and reputation. Basically calling me a wife beater which I never was (I retaliated with a slap once against her continual slapping and punching of me over years). She made the same accusations against her children's dad too.
I have hard evidence that could ruin the stories she has written about me but although I've denied her allegations I won't defend the divorce as I want rid of her out of my life forever.
I do wonder though if I should make some of that evidence public and too go ahead and ruin her. I always knew in my mind someday something in that relationship would bite me so very paranoid I documented everything. Now I realise I was right to do that.
But how far would you go or would you just leave it and not give her any reaction?
