If you make one move or threaten her in ANY way, she will use it against you. Bet on it. Before you two fall into the same cycle of events, calmly explain that you will call the police and have her arrested. Once that is on her record, she is on the defensive. And you will be viewed as the victim.
People naturally assume that husbands are the aggressors and the wives are the victims.
You need to get solid legal documentation that this is not true in your case. Do not cut your own throat by doing something rash or acting out of anger. I wouldn't lay a finger on her. If you make one move or threaten her in ANY way, she will use it against you. Bet on it.
