Just a guess.
They didn't get it from the article. It mentions one arguement, one incident of "push and shove". I think some here are launching on emotion and a predisposed fantasy of "previous behaviour".
Everyone, Get yourselves in control!
I agree 100%. Normal, stable people don't just go around threatening to kill the family pets. Note - there is a big difference between pets and "animals". I am surprised that some are confusing the two!
On my part, yes. My personal experience is that controlling types will invariably threaten those things you hold dear as a means of controlling you. During my marriage it wasn't just my pets were threatened.
Looking back, I struggle with my mindset that kept me locked in that relationship and kept me from making rational judgments.
