Sure it is in us because of evolution, but the reaction of others to a man showing his "weakness" is also part of it. A male does not only feel Inadequate if he shows weaknesses, he is also seen by other as Inadequate. And maybe he is. Imagine if woman would tend to males who show theyr weakness, how far would we have come in evolution?

But talking and listening is key in any relationship and if there is true love, then there is always a way.

Have a good Day!
