1. Does the roomate have your ss #?
2. HAve you lived there long enough to have had your driver's license at that address?
If you are sure you have no written rental agreement, and can answer "No" to both the above, and if you are for real, just go off into the sunset.
I hate the idea of running, but you will be overwhelmed. Until a lot of "authorities" wise up, all a female (why I agree with your putting that in the post, it changes the rules. I did not read the other thread about "fighting...etc.) has to do is mention the words "harassment" or "abuse" and you are FINISHED. No one will even hear, let alone heed your side.
When dealing with roomates, have no agreement or, if you must have one, have as little information as possible on it. Even if the lease was yours, she could make a lot of trouble with the right words. Use a cell phone. All bills to a PO box, preferably tied to another address.
