In reading the Finlay filing I was reminded of the incident where the former Mrs. Tiger Woods, Elin Nordegren, upon learning of his multiple infidelities, clawed his face and went after him with a golf club, causing him to exit the house abruptly and crash his SUV. She claimed she had busted the SUV's window with the club in an effort to help her husband, but it didn't look that way to the cops, who wouldn't let her ride in the ambulance with him. Woods did and said the appropriate things to protect his wife. However, it was by all reports uncharacteristic behavior by Nordegren under great stress and an isolated incident. It was wrong, even so, and it's hard not to think that Nordegren took for granted that whatever her husband's problems keeping it in his pants, he would not retaliate in kind when she attacked him or risk hurting her trying to protect himself; he did the only thing he could do if he couldn't calm her down, which was get out of there.
Male-on-female domestic violence, in comparison, tends to follow a repetitive pattern of seduction and battery designed to control the woman physically and psychologically over time. Female-on-male domestic violence tends to be more driven by impulse or self-defense. If even half of what Finlay alleges is true and reported in context, I would say that Waterbury doesn't fit into either category: She needs help. If it's true that she lied when she claimed Finlay had been physically abusive when in fact the reverse was the truth, that's........not good.
I will say she gave him at least one piece of sound advice:
Wise words, Alex.
