I don’t think this is a fair description of how DV works, especially in this situation. I don’t think we are seeing “novel” DV, normally non-violent people pushed to the edge. It’s more that victims of DV learn techniques to minimize/deescalate-they know when to leave, or to get the abuser out of the house, or invite people over-and they can’t use those techniques. Past that, if you are a person whole already deals with frustration and lack of control by physically lashing out, well, this is a time of extraordinary frustration and lack of control for everyone. There’s also the increased opportunity for sexual abuse.
I worry a lot about some of my students. Over the years, I’ve read so many college essays that talked about “I learned not to go home” or “school was important because it gave me an excuse not to go home”
