Gerk,

You need plan B/D more than anybody. Put her crap in storage, mail her the key, pay for one month, and then change all your contact information and go to a very dark plan B/D. Trust me, this tiger just showed her true stripes. She's a truly awful person. Even if you would have gotten back together, she would have treated you like this in the future. She's a very selfish and vindictive human being with no compassion or empathy. You just hadn't pissed her off much before. Now that you have, you get the b!tch treatment. It would have been coming anyway. Just move on and let her rot. The only way to get over her will be to cut all communication with her. Trust me, after 6 months of NC for YOU to defog, you'll be thanking your lucky stars that you are free of her. Choose more wisely next time. I know it sucks right now, but there is light at the end of the tunnel.
