Of course we can never truly know- but we can observe. For instance, young men are 4 times more likely to commit suicide than women-as they find the expectations of them are so high and multiple, and nowdays even confusing, expected still to be the provider, the 'strong' one, and at the same time to be gentle and considerate, etc, and also because they find it so difficult to ask for help, from family, friends or professionals, as it is a sign of weakness.
If a woman decides to stay at home to bring up children, that is totally fine. If she decides to go back to work, all fine too. But if a man decides (hopefully with his wife) to be a stay at home dad- it can, still, be a very difficult option on so many levels.
