I can see this. Se role gets out of hand when highly unhealthy, I attempted to stab some guy with scissors once, and other time i kinda did stab someone but that blade wasn't sharpened, or else i'd have been sent to some mental asylum (i was in high school at the moment).
I have never gotten physical with any ex though, nor any woman. But i've had women get physical with me. One of them being my sister.
