Bachelor from WikiPedia:

A bachelor is a man above the age of majority who has never been married (see single).

The term is sometimes restricted to men who do not have and are not actively seeking a spouse or other personal partner. For example, men who are in a committed relationship with a personal partner (female or male) to whom they are not married are no longer generally considered "bachelors,"[citation needed] but neither are they considered married. Thus, a broad grey, unnamed status has emerged between the concepts of "bachelor" and "married man."

Research done by sociologists Richard Pitt and Elizabeth Borland sharpens the definition of bachelor to mean "men who live independently, outside of their parents' home and other institutional settings, who are neither married nor cohabitating" for just this reason. They discovered that these bachelors were more liberal in their attitudes towards women's roles in society; this was not the case for those men who were only "unmarried".
