We men are not great at expressing our emotions in words. We are more comfortable with deeds and actions than trying to express complex emotional states we are already uncomfortable examining. We are raised to be strong and unshakable bastions of safety that our friends, family and lovers can retreat to when they are in pain or danger. Being vulnerable and open is difficult for us, but not impossible. It is fairly obvious when we have opened the castle gates of our hearts and let someone in.
