virago-- 1. A loud, overbearing woman
Also--harpy, ogress, scold, shrew, termangent, vixen, Xanthippe
I prefer to be blunter--this woman is just an a-hole, forgive my language. And I'm sure her, what was it, 2%, will be soooo valuable (sarcasm).
while I am partial to harpy, a-hole covers the bases nicely. I can see why her ex was pushed over the edge and now seeks solace with other men. Still wondering why Slick Willie never did likewise, but then, that unholy union was a marriage in name only.
