Have you ever told her that her behaviour is so bad that it's seriously making you want to leave? How do you think she would react to this, would it make her think or would it just trigger her more?
Yes, she is aware. I have been asking her to leave for over one year now. I think she wasn't taking it too seriously because I would say it in the conflict days only, so she didn't see consistency. It's very difficult to communicate it without generating an angry and childish "I also don't want you" response. But the trick is to wait for those days in which she is trying to reapproximate (pull mode) and then communicate it right when reconciliation is expected. With that approach, she then took it seriously. After many attempts to talk it out with her, we have actually made an agreement, but I'll leave that to another post. Don't want to add a spoiler here.
As for her being more quiet when full of cold, I think being ill makes us all a lot quieter and not so bothered about anything - we just want to get well again. I'm sure you're appreciating the calm period though.
Yes, when she is ill, she doesn't shout as much and has less energy but still says awful stuff.
But what happened yesterday was a sudden change. Suddenly she jumped into pull mode, full strength. I could see it in her eyes, so I kissed her and confirmed the reversal. Surprised with the speed of the unflip (about one hour), I waited for the next day and then asked her what happened. With some effort, we figured out it was because she talked to the kids a bit in the kitchen, and that conversation cooled her off. As she talks to them, she also gets self-insight and feels guilty for making them hear all of the disgusting stuff that's directed to me during her outbursts.



but yeah, there's always those doubts, especially with the way people with BPD just move on like nothing happened and 'seem' happy. It makes you think, 'damn, was I really that bad and crazy? they were right and are doing way better while I'm here crushed'.
