Just to play devil's advocate a bit and to add a bit of contrast, I still don't get why the advice on Mumsnet threads is often that the poster should leave. I have often thought this.
I'm sure tomorrow there will be a problem: perhaps a poster's partner says her friend is the best-looking woman he's ever seen and refuses to unsay it or qualify the comment. Or, hubby is depressed and just watches TV after work. (He's scared his business will fold during Covid restrictions - unsurprisingly. )The advice is often that it is so unreasonable, they should go. Especially if the problem can't be discussed. Or, husband only likes making love if she pretends to be a nurse, and she doesn't like doing this. But he's a great and responsible dad. The advice will come back to consider leaving, because sexual incompatibility, even if it develops late, is a deal breaker. Or husband keeps grabbing my bum, someone might post. 'That's not on; leave' will come the reply.
You are blessed if your partner wants to discuss issues between you. You can't work on your marriage if you're talking to a brick wall, because your other half refuses or doesn't have the introspective skills to engage with you.
On the one hand, some threads will be decrying the way that women are treated, patronised, cat-called by men, in public by people they don't know, or at home or in the workplace. On the other hand, there will be a view that marriage will be fine if you decide you are going to stick at it.
I think the truth is that we all ought to try hard to work at marriage and one stable lifelong marriage is best. However, parents are under greater pressure than forty years ago to provide an emotionally calm environment for their children. In terms of child experts, any kind of tension is bad for the kids, so many women do leave marriages in which the man has become emotionally aggressive or controlling.
