You haven't asked a question here, which makes it harder to give an answer. (Please see this Guide: www.avvo.com/legal-guides/ugc/five-tips-for-how... .) However, here is what you must do:
First, do not talk to this person again, or have any contact with her. If you see her coming, go the other way. Do not invite further accusations.
Second, email the site admins and ask them to take down this post, or at least edit it to remove this person's name. You should never, ever post your name, or the name of someone else in a legal dispute, on the internet. This is not a secure forum. It's open for everyone to see. So this could be found and traced back to you, and used against you somehow.
Finally, and most importantly, consult with a criminal defense attorney in private. It sounds like you're charged with a crime, for which you absolutely must have counsel to defend yourself. Until you do this, do not discuss this matter with anyone else. That includes discussing it on the internet, and it especially includes talking to the police. DO NOT TALK TO THE POLICE. If they try to talk to you, you must say "I'm sorry, but I don't want to answer any questions or consent to any searches, and I'd like to speak to a lawyer, please." Or, if you want to be technical, say "I'm invoking my right to remain silent and my right to counsel." Say that, ONLY that, then STOP TALKING. Do not try to explain yourself. Do not give excuses or explanations. Do not tell your side of the story. SHUT UP.
Talking to the police without your own lawyer present can never, ever help you. The police are allowed to lie to you and trick you to get you to make self-incriminating statements. They can misrepresent what evidence they have. Or they will say, look, I'm sure this is all a misunderstanding, why don't you tell me your side of it - and then you'll say something they can use against you, and lose any chance of a defense. Do not fall for it. Do not talk to the police. Ask for a lawyer. Shut your pie-hole. Have I made myself clear?
Why do you need a lawyer? Only a lawyer can hold the police accountable for statements they may make to you about what evidence they have, or don't have. If you say one thing about a conversation, and a police officer says another, who do you think the court is going to believe? The police officer who's been on the force for ten years, or someone who's accused of being a criminal? People always believe officers above ordinary citizens (even though officers lie fairly commonly), if only because officers tend to be more coherent and articulate in their presentation. Only a lawyer can be sure of getting access to evidence the police hold that might help you. And only a lawyer can tell you what it's safe to say, and when you need to keep your gob shut (answer: most of the time; but it's impossible to give specifics without being there).
You have the right to be appointed a lawyer, at taxpayer expense, if you're charged with a crime. You can ask about this at the first court appearance, if you haven't gotten one yet, but you really want to be proactive and talk to a defense lawyer first thing.
