We don't know that. Scripture is very silent on Peter's wife's status, her life or even her name. One tradition has her dead before Jesus called Peter, making him a widower. His mother in law was living in Peter's house; that's the most that we can rely on.
God bless you Mark. Have a great weekend. I respectfully disagree.
In the 1st century Jewish culture it was normal to be married and to have children, in fact, Rabbinical law required that Rabbis be married back then.
