I mean that the male identity doesn't seem to have evolved much beyond breadwinner, watch sport,drink.
I think you're pretty much spot on with your last post.
Over the past few decades, women have become more financially, socially and professionally independent and have less 'need' on a man in their lives (speaking from a totally heteronormative perspective here for the purposes of this particular discussion). Having done so, we now seek 'equality' in our relationships in a way that in the past we might have been required to seek someone to provide for an protect us.
The result is frustration for women who are seeking 'a real man' in terms of one who expects to do their fair share of housework and childrearing, one who doesn't think it's weak to discuss their emotions and one who presents as a fully functioning human, and frustration for men who feel angry that their natural and inherent 'superiority' as Men is no longer recognised/respected, thus giving rise to the MRA stuff.
Many men want to emulate the relationship model that they saw growing up - Dad goes to work, goes out with his mates, does what he likes with no questions asked, while The Wife stays at home, knows her place, keeps quiet and lets him have his space. And this basic model was seen at all levels of society.
Whereas women are actively seeking to break free from this and create an new egalitarian relationship model.
Until men in general accept that this has changed and realise the benefits of the new model, then I don't think relationships between men and women will work.
