And I explained why I was asking, how it came across. And she just said "it is what it is".
Her reaction to my question seems very much like the response to your "why".
In my case, though, I'm not sure if she really didn't understand that it might not be obvious to me what she meant, or if she really was being sarcastic but wouldn't admit it.
Or she might have been afraid that you were going to somehow antagonize her after she answered or something.
Normally I'm okay with questions, but I have had a few people ask me questions in a seriously antagonistic way, and then I can get sensitive over those questions, even if a later questioner is asking them innocently.
Her response sounds a lot like "It's a long story," which is translated usually as "I don't want to talk about it."
What frustrated me very much though once, was when there was a guy who made posts with 'apostrophes' like 'these' around half the words in them. I asked whether they were for sarcasm, emphasis, attempt to set the words apart from other words, or to say he didn't really believe the word. He got really angry at me and told me that I was not respecting his neurodiversity. Which startled me, but I guess maybe he'd been asked those questions in an antagonistic way at some point and figured I was too. I was just trying to figure out his posts. (He'd also complain if his posts were ignored or misunderstood.)
