There is a really extensive feature in today's Times about the state of 'men's happiness' these days. It's really interesting reading. It's in one of the supplements. Just thought I'd recommend it if you can still get your hands on it. Saturday's Times.
The gist of it is that women have overtaken men in terms of social mobility, friendships, jobs, 'knowing' their roles in life and that men are floundering. Men no longer have strong social networks and rely on their partners for their social lives and find little satisfaction outside of work.
One thing that really rang true to me was how many men rely on their partners for their social life. How few friends they stay in contact with and how little socialising they instigate for themselves.
Really worth reading.
