Findlaw carries the AP story on women being the plaintiff in divorces two-thirds of the time (for the over age 40 group).
Chaka Ferguson writes (excerpt):
The survey found that women over age 40 seemed more aware of problems in their marriages, while men were more likely to be caught off-guard by their divorces. Twenty-six percent of men said they “never saw it coming,” compared with 14 percent of women.
The AARP study found that most women said they filed for divorces because of physical or emotional abuse, infidelity or drug and alcohol abuse. Men said they sought divorces because they fell out love, they had different values or lifestyles or infidelity.
