Everybody is going nuts over this story, that of the Astronaut love triangle. They shouldn't.
The real novelty seems to be that this story is coming from an upper-middle class person's actions, and we aren't accustomed to hearing about this type of law-breaking behavior from these people.
But it can happen anywhere. I suggest this story is evidence that controlling behavior—shown here in a stalking context—can happen to or from anyone, regardless of socioeconomic status.
The real sad thing is that this story is sensational. We should be more aware of the problem's prevalence rather than marvel at the unusual(ly reported) context.
It's also unexpected because of the extensive battery of psychological tests that astronauts have to pass. It is surprising to me that a supposedly stable person could degenerate to such a degree.
