Hi Pook,
I think that repression of traumas is very common, as is the general concept of repression. In addition, if you were "out of it" for a while, it's easy to understand why your memories of events surrounding that scary incident are hazy. On top of that, since you were operating in "survival mode" for such a long time, it was normal for you to focus on just getting through the day, rather than reflect or piece together a tapestry of dysfunction. As you know, many BPD behaviors don't seem logical, at least on the surface.
I guess it should be no surprise to you that your ex blames you for trying to throw her out. I bet she blames you for throwing her out several times, even if the fact patterns don't line up. The pwBPD in my life says the exact same thing, when typically the fact pattern is completely opposite (e.g. when I've asked her not to leave our home after an angry outburst). You know how blaming others is a common BPD tactic. Their narrative is that others are ruining their life and being abusive, when usually the opposite is true: she's acting horrendously and treating her loved ones like crap.
When BPD behaviors started to emerge in my young adult stepdaughter, I was alarmed by the string of increasingly dysfunctional incidents, as well as by the angry rages she displayed. At first, I took everything she said at face value. But over time, I saw how fact patterns just didn't seem to line up. As I learned more information, sometimes months after certain incidents, I was able to go back and re-interpret her stories with that knowledge. Then I understood how her stories and accusations were wildly distorted, and often projections. I saw how what she was purportedly upset about wasn't really the problem--it was deflection from something more serious that she was trying to hide, from herself and others. I guess I was able to see the patterns because I wasn't the object of her rages. Maybe I saw more clearly than the other loved ones around me because of that.
I'm not sure how best to deal with traumas and confusing memories except to amp up self-care, whatever that looks like.



I would suggest first reading the many posts here - you'll find them informative and no doubt you'll be able to relate your own experiences. BPD follows a very repetitive script and we've all experienced the results so you're in sympathetic company. You'll also find out how to cope with the BPD outbursts and hopefully reduce the conflict.
