Men can theoretically father thousands of children. They just don't have the reality that each birth could kill them, or leave them with physical trauma like a fistula or a prolapse, often permanent physical changes, post natal depression etc. They may not even know they have children.
Men are more likely to get up and go, abandoning wife and children, starting side families, having new relationships and dropping the older children than women are. Being left holding the baby is generally done to women.
I think they are more inclined to compartmentalise. Wife & kids in one compartment. Bit on the side in another. SO many 'I've discovered my husband is having an affair' threads here.
Even those who push for 50/50 - how often do they realistically stick to that arrangement, and do their half of the parenting?
I am convinced that (whatever they may say), not having gestated, laboured, recovered from the experience, breastfed, been all touched out etc, men do not have the same visceral connection to their children that women have.
I'm also convinced that many men see women and children as things, property, possessions, to be owned, controlled and disposed of at will.
And if a woman leaves (which we know is the most dangerous time), I think they see her taking herself away as him being deprived of his rightfully owned property. And if she takes the children too ...The 'if I can't have them nobody can' family annihilator is overwhelmingly male.
Then there is the well known thing about true colours only showing when she becomes pregnant or the new baby arrives. So many get used to being the centre of attention, and then finding a whole new person has taken that away can come as a nasty shock. And as for the realisation that someone else now has first dibs on the boobs ...
It's almost as though they've sleepwalked into the reality of a screaming pooping weeing wriggling puking sleep denier and it never even occurred to them that this thing that's been happening for millions of years is going to happen to them.
So how the hell do we all get this sorted out?? Where do we even start?
