hi LionHeart2929 and

sometimes people wake up on the wrong side of the bed. and when someone with BPD traits does, they can be like an irritated ball of emotion spoiling for a fight. its anxiety inducing for the other party (you) because you can see it coming and building.
it sounds like you were pretty good about anticipating this, defusing, and not escalating.
Anyways by the end of this and every other one of these fights she runs loops around me and says she didnt do it, she did nothing wrong. And me panicing or stuttering because im worried about upsetting her or telling her to be careful or that shes getting a bit to vicous for the kids is abusive in itself. she just says no she didnt, that I do the same, or that im overreacting. Every fight changes to "im only mad because you treat me like im going to explode."
what i am confused by is what led to this. it went from her blowing off steam where you were mostly giving her a wide berth to an argument. who initiated that conversation and how did it play out?
The only way to stop these episodes is to say it was all my fault and im sorry.
i would not necessarily focusing on stopping each episode, and im not sure that you can. you can change your response, you can limit your engagement, you have a lot of options. arguing or fighting (or even showing love) with someone who is emotionally dysregulated can escalate things. dont try to put out every fire; you cant. let some of them burn themselves out and clean it up later when everyone is back to baseline.
