Probably preaching to the converted here but I just wondered if anyone else had read the book or seen the film (1970s film so hard to get hold of but you can buy it online for a few quid). It was famous for a while but haven't seen it mentioned in discussions in recent years, perhaps it's seen as "out of date"
I was obsessed with it in my teens back in the 80s and my mother borrowed it at one point and it made her cry because it was so close to home.
It's the story of a suburban housewife in the 1950s who makes friends with other mothers, who contend with infidelity, abortion, DV, behind closed doors, how powerless they are, and how she has a political awakening when she goes to university after divorce and finds fresh thinking from the new feminists. It's terrifically powerful.
If you haven't happened to come across it I urge you to read it. A slice of history and many reminders of the insidious - and blatant power of the patriarchy.
