grass widow

grass widow idiom
A woman who is separated from her husband, either by divorce or temporary absence. For example, She's a grass widow these days, with Herb traveling to golf tournaments all over the country. The expression dates from the 16th century, when it referred to the mother of an illegitimate child, grass presumably alluding to the open-air setting of the child's conception.
