Many many cases of false accusations of DV. If the marriage is on the rocks most people start planning. To get custody, to get the big alimony settlement, your case is strengthend with a DV charge. So it’s an easy thing to start a fight, go into another room and injured yourself then call 911. Police show up, arrest and charge the spouse. Happens all the time!
I had a buddy who decided to divorce. To avoid that exact scenario he moved out of the house one weekend when his wife was out of town. He then refused to be alone with her ever again. He would only meet her if necessary in a public place.
That was smart of him.
