My Polish woman has a temper that would send anyone into shock, quick isn't the word. Thankfully it's like water off a ducks back with me, which only makes her even worse.
Women seek attention; even when it's negative. She is looking for you to counteract her emotional diatribes but since you don't, she goes ballistic. The worst thing anyone can do to a woman is to ignore her. This drives women crazy.
I think there's a pressure valve in her head
This valve is on "high", can you adjust it to "low"?.,....and is this woman worth keeping?
I've got to be careful otherwise she can be moody for days...
She is emotionally controlling you. Evidently you are smarter than she is and the only way she can be dominating is by going 'nuts'. You shouldn't have to "be careful" as you put it.
