No, it’s not reasonable to assume that poverty is a cause based on a study that says it wasn’t.
Sir, I understand you are busy and you probably missed what I said,

Please note that poverty itself probably doesn't cause brain development to accelerate.

And low-income areas and countries don't have higher rates of violence and child abuse?

differences in socioeconomic status.
Here is what the nature paper says " We argue that higher childhood SES is associated with protracted structural brain development and a prolonged trajectory of functional network segregation, ultimately leading to more efficient cortical networks in adulthood. We hypothesize that greater exposure to chronic stress accelerates brain maturation, whereas greater access to novel positive experiences decelerates maturation."

It’s all about differences in averages
So what is the average in Mexico or in low-income areas?
I didn’t miss what you said at all. You are arguing that, despite what papers you cite to say, poverty causes the accelerated development. If poverty caused the accelerated brain development through the mechanism you suggest, then the papers wouldn’t say what they say.
No, you’re still not understanding. The scientific papers are about averages. They are meaningless in determining whether the young woman you dated experienced the accelerated brain development and how that affected her interactions with you. The papers cannot do what you want them to.
As for the nature paper, again you are ignoring critical language in the paper, including this:
In this Perspective, we have considered evidence that experiences associated with childhood SES affect not only the outcome but also the pace of brain development, with potential influences on brain plasticity throughout life. We argue that low exposure to stress and high exposure to novel positive experiences promote protracted structural brain development, which gives rise to a later, longer trajectory of functional network segregation, ultimately leading to more efficient cortical networks in adulthood.
However, this model is based on incomplete data. Studies to date have not been fully representative of human diversity, focusing primarily on Western populations with nutritional excess168,169,170. Studies have also been limited by methodological challenges, cross-sectional samples, lack of connection to adult research and correlational designs. Below, we discuss promising approaches to overcome these limitations and directly test our hypotheses in future research.
The authors themselves say that they have a hypothetical model that they argue may have explanatory value, but there isn’t sufficient data available to evaluate their hypothesis. That doesn’t permit you to draw sweeping conclusions about any groups of people, let alone your former girlfriend.
Averages of some unspecified index numbers for our neighborhoods or Mexico aren’t going to tell you anything. I’m certainly not going spend time researching those questions, even assuming that such numbers exist.
