male suicide and marriage breakdown

From an 'on line' opinion page:

Male suicide is a real problem and should be funded, researched and managed to reduce it. BUT men have been suiciding at a rate of four men to every one woman SINCE the 1920's when statistics began. The biggest exception to this was the Second World War when suicide rates dropped the most and the 1960's when male suicides dropped and female suicides rose to the ratio of 2 male to one female. So other factors are causing it. The number one correlation of spikes of suicides in men is with economic downturns.

Marriage breakup is initiated by the woman in 64% of the cases but there are still 36% of women who are left-a statistically significant group. There are also many women who leave due to the violence, drunkenness, drug addiction or mental illness of their partner (men leave for this reason too). These two groups obviously need a different approach than your punishing "why leave? Or better still leave the children with the father."

There are people who leave their partners when for all concerned it would have been better to stay. There needs to be something done to help reduce that incidence.

The lower life expectancy of men isn't just for separated fathers but *never married* men too-it's quite significant. But the statistics for women show *never married* and separated women live longer than married women. Now why would that be? Why does marriage make women die younger?
