why men are more communitive with friends than girlfriends?

Because in most cases, anything you reveal and share about your worries and vulnerabilities with a girlfriend definitely will be used to harm you in the future. Women keep records. Men do not. Not nearly as often, anyway. And women also mostly hate it when men look weak in any way. They believe even the hint of a man having emotions as their having to do “emotional labor.”

Other than my present partner (which is one of the many reasons I’m still with her), 100% of the women I’ve dated or been a relationship with have been this way.

Why, I do not know. But it seems incredibly common with women. It must have to do with socialization but even with as many women friends as I have, I don’t understand it — since behaving this way harms the woman in question too.
