Was Jesus Married?

I find it funny how some will say there is no evidence that Jesus Christ ever existed, but now these same people can tell you He was married and even how many children He had

Jesus was called a rabbi, but was never a student of the temple, the fact was at the age of 12 He knew more than the teachers of the Temple. And at the age of 12 He pretty much told His earthly father joseph that He, (Jesus) must be about His Fathers business.

Betty Crocker was a fictional character yet people have said how many offspring she has

If Jesus was fictional then the point of Him being married is mute, and one could make up what ever story they wanted.

And to my knowledge, there are no first or second century FULLY existing copies of the Gospels, so how could any scholar say this story was added?
