Thinking more about my exhusband and his behaviour. He never respected my MIL and ended up being abusive towards me in similar ways.
Now I see a lot of younger men in their 20s talking about going no contact with their mums. I'm not sure if this is a recent thing but it seems to be popular recently. If they're going to treat the most important woman in their lives (as children, before their wives.. of course the partner should be the priority after that, but it still doesn't make it okay for men to blatantly disrespect and use sexist thinking in terms of their mums) that poorly, who's to say that they won't act the same towards their partners?
I saw an article the other day about all these adults who go 'no contact' and I think it could be beneficial or necessary for people with fathers who were very abusive, but it seems like they're cutting contact for any little reason. This plus the accepted misogynistic language of teenage boys who also often disrespect their mums.. thankfully that language is now openly criticised with shows like adolescence and discussions around social media but no one is tackling how acceptable it is for adults, particularly men, to suddenly hate their mums and to feel justified in using derogatory language towards them. It seems like 'no contact ' is a permanent thing too and not just taking a small break from your loved ones.
On the flip side, I do think that 'mummy's boys' are an issue. My younger brother showed a lot of codependant behaviour in retrospect. He's never moved out although he solely pays the bills now instead. Our mum does all his cooking and laundry (normal in our culture but it really shouldn't be!) and I honestly feel for SIL who also lives there. I see both sides of the coin and both extremes seem equally as toxic
