I saw this study mentioned on the internet and was very surprised by the results.  It suggests that in marriages where the husband does not work full time, the risk of divorce increases by a third.

I do wonder if this statistic is less about wife's earning more than their husband and this is more a recognition of the impact changes in life can cause.  For example, either spouse having health difficulties or family commitments and changing work hours to deal with this, or working changes due to approach of retirement.  These factors are themselves possible causes of relationship difficulties.

If you have any questions about divorce or family separation, please do not hesitate to contact me.
