Oh, can I sound off here?! I have my PIL (exPIL I guess - I'm recently separated) for the day. I have just had a car journey of relationship advice from my FIL.... 
It's a cultural thing apparently. He has seen so many women do it to their husbands . Women from "male dominated cultures view their husbands not as partners but as the opponent" was the central theme.
Like his wife. And the woman down the road. She's all bum and tits but she's sharp and she treats her husband like the enemy.
He sees it all over. Men work long hours and then come home to grief. Woman all do it. They don't mean to.
(It's the first time I've heard that description of the woman down the road. I've always been told how alike we are!
)
Oh my fucking god! Deep breaths.
