She would probably file a DVRO claiming abuse. It happens all the time. I have heard horror stories in messy D where the H will preemptively file a DVRO on the W to beat her to the punch so to speak. There are routes to combat a potential DVRO, but I am not a L.
Bo,
It sounds like your W hasn't consulted a L because she either doesn't know what the heck she is talking about, she is attempting to manipulate you, or both. Sounds like she is also projecting her guilt. Take all the statements you posted and bring them to your L. Also maybe ask the L about the legality of recording these threats with your phone.
