Men are notorious for not expressing their feelings well.
A big reason for that is they were never taught how to do it as boys. No one tells them, “You’re gonna feel anger and grief, and here’s how you handle those emotions.” When boys get upset and shove their sister or backtalk their teacher, their behavior gets scolded, but no one teaches them how to harness their emotion and channel it in positive ways.
I once heard a professional football player say that he struggled to manage his emotions because he was expected to be aggressive in his job each day but then switch it off before he returned home each night.
