Surely a relationship based on sexual coupling and child-rearing has a much higher risk of this than a friendship with someone of the same sex based on camaraderie and shared interests?
Yes, one would think so @thepeopleversuswork! I mean, sexual relationships/marriage are incredibly high stakes, and the fallout when things go wrong is potentially terrible, as one glance at the Relationships forum on here will tell you.
So it does feel deeply illogical that people who are in (or have formed in the past) committed relationships or married, particularly with children, talk about friendships as though those involved far too much risk, drama etc. And that anyone who has had a significant relationship or a marriage end would recognise how important friendships that aren't based on sexual fidelity and economic interdependence are ...?
I would be prepared to be that most of the time when people trot this out what they actually mean is that they don't want to have good friendships with other women because their spouse is threatened by it.
That hadn't occurred to me, but maybe you're right. It's an appalling thought, if so.
The other thing I sometimes find myself thinking about is a mindset that I associate with my mother's mindset and generation (she's in her late 70s, from a conservative, religious rural background, and met and married my father at 21) -- which is that young women need friends primarily so that they can have a social life that lets them meet men they can marry, and then after they marry they apparently 'naturally' retreat from friendships.
I think she finds it mysterious and possibly slightly improper that I, with a husband and young child, regularly go out at night to see my friends. Because in her view I'm 'settled' and no longer 'need' my friends.
