Sometimes in the middle of the maelstrom, these folks do hiccup up a bit of truth imho. Not always intentionally, usually not constructively with a 'so what I'm going to do better is...', often doesn't last long, , just a statement in the moment really like 'the sun is shining'. (I remember my xh saying two things in the early days before he stopped talking to me at all, both of which were quite true...that he could not be trusted with our relationship and that he wasn't the same person anymore.)
So what it means? It means that your w - at the moment - thinks she is flaky and unreliable. Which is probably from your POV completely accurate. And why nothing really important in your life or sanity should be contingent on anything she says or does. No more mind reading needed than that, I'd suggest, John.
