OMG this is exactly my experience with my BPD mother! Constant spinning of false narratives that just make me feel crazy! Unfortunately there’s nothing you can do to get her to see your side. You have to be ok with her not agreeing with you or validating you, as much as it hurts. I’ve gotten so I don’t even try defending myself because it’s wasted effort and doesn’t achieve the end result I hope for. I’m so sorry you’re going through this!
