For one thing, we don't know if she was Gentile or Jewish. Roman women were quite independent as we know. The situation suggests she was Gentile, as the Apostles were accused to introduce Jewish customs to the Romans, and the town is described as Roman colony. The name is obviously Greek. Also, the Apostles were preaching to the women assembled at the gate, and converted her singlely, but we cannot definitely say she was single. A reference is made to her family. She does indeed display independence.
But be it as it may, no one insists that a former temple virgin could not, never-ever, remain single and chaste into adulthood, just that to do what the Protoevangelium describes was the natural thing to do.
She may or may not have had a family, scripture says "household", which could be family, could be servants. At any rate, it wasn't unheard of to have women doing things besides cooking and cleaning. Women as we know, traveled with and supported Jesus and Paul. Martha's sister Mary, "chose the good part", became a disciple as did other women. We Protesant types don't have a domestic meltdown just thinking about it either. :)
