Dealing with a narcissist couple...

So one partner physically assaulted me, then falsely reported me to the police. The other thinks I deserved it. They are now trying to bully and manipulate my partner (who was there and saw exactly what happened) into breaking up with me.

The one that assaulted me is even claiming she feels unsafe because he continues to date me - meanwhile I am actually genuinely terrified of her and what she might do next.

Unfortunately my partner currently lives with them, so I am unable to say or do anything that may jeopardize his safety (and the police case is still open, although I went in voluntarily and explained my side, and have been noted as the victim although I'm listed as the suspect in the original report). I know at least 3 of my partner's friends will have been told the other two's version of things, but only one of them has reached out to him, and only very vaguely, so I have no idea who believes what about me.

So I'm sitting here, knowing a mutual friend sent them a screenshot of my Facebook post, unable to say anything because I don't know who knows what about the situation, scared to use my own social media without filtering out half my friends list. My partner and I are away together, they knew he was going away but not with me (until the screenshot), and he woke up to an abusive text from them. How is that supposed to help turn him to their side, exactly?

I just want this situation to be over. I just want to be left alone.
