It isn't that men don't like to talk, it is that the majority of people don't want to hear it. Women will listen to other women, offer words of comfort, but many will hear of a man's troubles and tell the man to "man up", "quit whining", and so that is the anticipated response when a man wants/needs to talk. Without motivation to open up, or with the expectation of rejection, there is no incentive to for the man to speak out. Similarly, by not having someone they can confide in, this leaves men also feeling unable to open up to other men, or feeling unable to know what to say when faced with someone who is brave enough to open up. This means often, by the time a man is at the point of opening up, of saying "I need help", they are already on the brink and possibly even planned action, because they are past the point of fearing the perceived negative outcomes. There are many who say a man should have said something sooner, who will say they would have listened if the man had spoken up, but if you are close enough to someone to think they could/would confide their deepest fears and emotions with you, then you should have realised there was something wrong. If someone is blind to the struggle and turmoil, then why would they expect the man to feel safe and supported in confiding?
