First, back then most Rabbis were married. So culturally speaking it would have been normal.
Second, if Jesus was married he likely would have had children. This would have created a problem because then people would say his children were literal grandchildren of God the Father. The orthodox view of Jesus’ nature is he was fully God and fully man. If he would have had children, his sons and daughters would have been a diluted version of the God-man’s nature and this would have created a controversy similar to the Immaculate Conception of Mary (i.e., Mary having been born without sin so as to be able to give birth to the Son of God).
Third, in the New Testament the Church is described as the bride of Christ (Eph. 5:21-33, specifically vv. 25-32). If Jesus had a human wife, then this theology would contradict reality and be confusing.
Finally, it is silly to speculate about the above because the fact of the matter is that no one who personally knew Jesus ever mentioned a wife or children. If he were married with children, wouldn’t this have been a significant detail for the Apostles or his disciples to mention?
