Most Helpful Guy
Simply put its experience with women. First from a young age we see all the assholes who play it cool and never show feelings, just apathy, get the girls. So we want to get tje girls to so we start immitating the apathetic guys because they have what women percieve as "confidence" but is really just apathy.
Sure we hear women go on and on, on tv, and in real life, about how they want a man to show his sensitive side, but when we do we are laighed at, mocked, and dumped for, you guessed it the apathetic guys. This happens a few times, and we get the message. No matter how much women say the want a man who is "in touch" with hos feelings they will cheat on, and leave him for the apathetic assholes who cares only for himself.3
