The thing is Females make decisions based on there heart in times like this, he needs to step away from the situation, and read it carefully and plan, no need for insults, abuse or illegal actions, then she wins, just write down a journal on what she does and what time.
I have had heaps of crazy sluts come to my work over the years and go off, just keep calm and you will see them crumble and cry, its a full-proof formula, they will kick and scream for attention then meltdown when its doesnt go there way.

You hurt her feelings cause your getting fucking a new girl (congrats by the way) she is enraged now and wants war, you cant have war if the other side wont fight.
dont accept her nastiness and she will fall off.
