I'm pretty sure I read something recently about either a gene being responsible, or a chemical state in the mind, that has become heavily associated with strong monogamous views. That's where both come from.
I need to ask, what defines a monogamous person? Is it the jealousy or hurt that occurs at the thought/action of a partner loving another? What is the push that a monogamous person has that makes them feel...monogamous?
Btw this doesn't mean I'm a polygamist. I just haven't had to experience such a mindset from either side yet.
