There are no biblical scriptures that mention whether Jesus was married, but in several circumstances he took over the role of a husband and women took over the role of wives. Jesus was also called "Rabbi", a title reserved for married men (John 1:38, John 1:49, John 3:2, John 6:25, John 20:16), and he also taught in the synagogue (Mark 6:2). According to Jewish law, a man had to be married to teach in the synagogue.

Jesus attended a wedding in Cana, where he performed his first miracle. His mother came to him when the wine was getting low. In Jewish custom, it is the groom that supplies the wine. Jesus responded that it wasn't yet time for him to come out, implying that he couldn't deal with it personally. Jesus's mother seems to be in charge of the wedding, as she commanded the servants to do whatever Jesus asked. He then told the six servants to fill six waterpots with water, and then to bring some to the person in charge of the wedding feast. Known as the master of the feast, it was their duty to arrange the tables and couches, determine the courses and taste the food. After tasting the water, then turned wine, the master of the feast seems genuinely surprised, wondering perhaps if someone else has brought wine to the wedding. The servants knew where the wine had come from and presumably told the master, at which point he summons the bridegroom. This strongly implies that the source of the wine was the bridegroom. It was to the bridegroom that the governor asks why the good wine was saved for later. (John 2)

Later, we find the story of Jesus spending time with Mary and Martha in a familial situation. Martha complains to Jesus that Mary should be helping her.

"[Martha's] sister, Mary, sat at the Lord’s feet, listening to what he taught. But Martha was distracted by the big dinner she was preparing. She came to Jesus and said, “Lord, doesn’t it seem unfair to you that my sister just sits here while I do all the work? Tell her to come and help me.” (Luke 10:39,40) This seems innocent enough, by why ask Jesus to intervene? Why is it the guest's responsibility?

It was Mary Magdalene, Joanna, and Mary the mother of James, who tended to the wive's function of preparing the body of Jesus for burial. (Luke 24)

There is isn't anything in the Bible to suggest that Mary of Bethany, sister of Martha, was Mary Magdalene, but there isn't anything that specifically excludes the possibility either. They both seem to have been wealthy women who supported Jesus financially.

When Jesus appeared to Mary Magdalene after his resurrection, he had not yet appeared to his father. Mary was the only person to see the resurrected Lord before he went to his father. She was there to prepare the body - something that only other men, or the deceased's spouse could do. She wept, when she discovered the tomb empty.

"Don't cling to me," Jesus said, "for I haven't yet ascended to the Father. But go find my brothers and tell them, 'I am ascending to my Father and your Father, to my God and your God.'"
(John 20:17)

It cannot be argued that Mary Magdalene didn't have a special relationship with Jesus, but here again, there is a danger of reading too much into it.

In the Gnostic gospels, Mary takes on a special relationship with Jesus, where nothing is hidden from her, because she is filled with light; but even in the Gnostic gospels there is no hint of marriage.

It would be unusual for a Jewish man to ignore the commandment to get married, but there was at least one community where the men abstained from marriage; the community of Qumran. The Essenes of Qumran wanted to be completely free of sexual temptation. They maintained their community through adoption. Some scholars have put forth the theory that John the Baptist spent time in Qumran, so it isn't far-fetched that Jesus might have been influenced by this community as well. Yet none of the gospels mention Jesus as special in this regard; not one lauds him as being celibate. What are we to conclude from the silence? Any conclusions would be sheer conjecture. It simply cannot be proven from the New Testament - one way or another - whether Jesus was married or not and whether he had children from such unions.
