Obviously some women are too but from anecdotal evidence & life experience, significantly more men than women seem to be excessively jealous, possessive and controlling.
Why do you think this is?
Obviously insecurity is a factor but most of us, including women, can be insecure to some extent; why does it seem to manifest itself in possessive, controlling behaviour to such an extent in men?
Is it an extreme form of mate guarding? (And the fact that makes might've been more likely to secure their mating 'rights' through aggression and intimidation than females)?
Is it that many men think on a more basic, level than women (so my dp says : you can never underestimate how simple and base we can be)?
Do you think these men can ever truly overcome (if they wanted to, which they don't seem to since they think they're on the right)?
