She's just doing this to try to get an edge in divorce negotiations by making you into a defendant on a criminal
case, which she thinks will cause the judge to see you as something less deserving than you are.
Frankly, though, she probably won't be able to do it, The police will listen to her for a bit, just long enough to hear that you were lawfully married through all of this and are now in litigation, and they will send her away and tell her to deal with this in family court
I can't guarantee you that, of course, but that's how I've always seen these kinds of claims under these kinds of circumstances play out. As a criminal case, this is a loser and DAs don't like to waste the public's time and the county's money defending against something they can't win. The average jury will see this for what it is, which would mean that they won't convict.
Look for a divorce lawyer and have as little to do with her as possible right now. Don't let her push your buttons and don't give her any new ammuniton to go to the police. If all she has is what you've said above, like I have already said, she's likely to get absolutely nowhere with it.
