I get what you mean, stress for the cortisol, anxiety for the adrenaline type deal. And, yeah, I do agree that such a temperament/character/neurochemical inclination seeks these situations for different reasons.

But I’ve also seen plenty of cases where it was just based on a belief, they were convinced that a relationship reached a breaking point once the chemical ecstasy started to die down. The people holding it were obviously suffering because of it (though not fully aware of this relationship) and genuinely wanted to find a fix. Unfortunately, they went from disappointment to disappointment when the inevitable kept happening.

It’s also why I only have questions, there are layers upon layers of nuance with subjects like this…
