There is a widespread frustration among men regarding the mixed messages we get, especially from women, on how we are supposed to open up more emotionally. We are told to communicate and express our feelings, but often face backlash immediately when what we say is twisted into something we never meant, and then long term is used against us.
Women say they would rather be alone in the woods with a bear than with a man. Men would rather discuss their concerns and vulnerabilities face-to-face with a rattlesnake than with the stereotypical woman, but they won't say it out loud because women would use that against them, too.
Not all women are like this, of course, but there are enough such women in our lives. It doesn't just mean romantic partners. Parents, siblings, gossips next door, co-workers... This gets reinforced all too often. If we still manage to trust someone enough to speak, and that trust is broken, it will never be back. Ever.
