She probably would. Because there’s always some incident at the root of the rage that, no matter how trivial, can be thought of as the root cause. See the bit about not getting milk in my first post.
I’m just whining. Most of the time she’s great. She’s fantastic. Some of the time she’s nuts. That’s how it is.
Just a thought. Have you asked whether she remembers being mad at you last tuesday (or whatever)? Was does she say? Does she remember being angry at all? If yes, does the item that made her angry seem just as important to her now?
Take a look at this emotional abuse website, Saintly Loser. Your wife might be great three weeks of the month, but one week of the month she is what sounds like emotionally abusive, and regardless of the cause, she needs to find a way to deal with it (other than treating you like her emotional punching bag). If the sexes were reversed here, and a woman was telling us that her husband drinks one week of the month and treats her like shit that week, I’d be saying the same things - this isn’t healthy for your relationship long-term, and it needs to be dealt with.
If she is completely unaware of how bad she gets, maybe try filming her.
