It's sad, but not uncommon, to see a spouse turn on you in these types of situations. Not sure there is much you can do to get her to act differently, but you do need to protect yourself. If your W is making false accusations about abuse, then she is capable of anything. I would stay away from her, unless in public settings, or with a reliable adult witness. Also suggest carrying a VAR (voice activated recorder) in your pocket, just in case she tries to entrap you into something.
Other than that, keep up with DBing, focus on yourself, and hopefully she will eventually settle down. I feel for you.
