Historic ‘stoic male’ personas existed for a reason. Because in many situations, it works. Despite the complaining.
And being less ‘emotionally connected’ is valuable when people use that connection to exploit or hurt you. A very common experience for many men.
That people (especially women) then complain you won’t open up to them is a riot in those situations because it’s like someone complaining you keep putting on your bullet proof vest - while they keep shooting at you.
Historic male mental health issues also resulted. But notably, folks depending on the stoic persona for their own wellbeing would typically throw you under the bus for those issues too.
“How dare you get mad! You’re a dangerous threat!” says the person constantly harassing the person, or the boss putting you in worse and worse work conditions while pretending they are doing you a favor, etc.
They do that, of course, because mad people actually fight back. But if you need the job or are dependent on the relationship…
As many men have experienced, the only way to ‘win’ is shut off caring about what people say on that front - among other emotions.
