Jesus said that the foxes have holes and the birds have nests, but He didn’t have a place to lay His head. Would Jesus have had a homeless wife and children? No. That would be irresponsible and that would be a sin.
Add to that, on the cross, He turns familial responsibility of His mother over to John, so that she would have someone to provide for her. He doesn't mention anyone taking care of a wife. Mary Magdalene, whom many "scholars" seem to list as the front runner in the wife category was standing right there. John 19:25-27
There isn't the slightest hint in the canonical books of the New Testament that Jesus was married. If He had been, there would have been no reason for them to suppress the information--it would have simply been accepted. His wife would have been mentioned in Acts--she isn't because she didn't exist.
St. Peter was married--that was not suppressed.
There is no reason to think John the Baptist was married, but he doesn't attract the same interest.
