Dude. I can’t tell if you’re willfully misunderstanding, so I’m gonna try this.
Women want men to open up and share emotions, yes. Sharing emotions in a healthy way means saying what you feel out loud, in words. It means separating your emotions from your actions..saying “when you do x, I feel why” not “how dare you make me feel y, you’re such a manipulative bitch.” It means sharing your emotions after you’ve processed them a bit so you’re not just dumping on someone else. Many men never learn these coping techniques as children. So when they express emotion, they do so as a child might, through pouting and tantrums.
Obviously this is unacceptable in an adult.
Therapy helps.
