There’s a lot of men who hide who they are. I dated a guy and we broke up. Later on when I refused to talk to him anymore for other reasons he stalked me. The guy I dated was kind and sweet. The man who yelled my name in the hallway, harassed me and my friends and stalked me is a different person then who I was dating.
Statistically, you know at least 2 guys who act like that whether you know it or not. Men typically do not act the same around other men in the same way that they would around women. Men who are attractive, extroverted, etc. have an easier time talking to women than guys who are shy, quite. The more confidence that guy has in himself the better off he’s gonna be with women and that leads to a lot of shitty people getting in relationships.
