My ex suffered from the double whammy of inability to manage money and inability to accept responsibility for her errors. Consequently, every month or so when the subject of finances (or lack thereof) would come about, I would suggest that I take over the financial planning for the family. Since she could not reconcile in her mind that she wasn't any good at it, she would fly into rages of fury (directed at me) that resulted in a house full of flying objects. I've had toasters, blenders, potted plants, kitchen knives, a vcr, crystal vases, and various other things thrown at me at high speeds and usually in combination. My only option was to duck and run for the door, it's not like you can hit back.
Yup. The last thing you should do is give her a scar to show police. Just leave.
Well, I did say "ex".
