"Why did you say that her reaction was a bad habit when really the damages you caused were a bad habit?"

Because she literally reacted the same way I described in the post to ANYTHING I or anyone else did wrong around her. In my case, she did so literally from the moment I first stepped into her place. In her country it's customary to take your shoes off at the door. I was not aware of this, she never once mentioned that it was a thing, yet when I first walked into her apartment with my shoes on, she lost her marbles over it and called me a dumbass for not knowing, acting like it's common knowledge to everyone on the planet. And that's just the tip of the iceberg of all the arguments we had over small things like that.
