There are many other academics who have propounded that Jesus was married, that Mary of Magdala was his wife, and that there are references in ancient documents to the effect that she was the head of the Christian group in Jerusalem after the crucifixion.
I don’t know why this would create a problem within the Christian community if it were true other than it would overturn some Church rules that were made up by men many years after the events.
Can’t be proven; can’t be disproven.
It seems unlikely to me that the Romans, knowing that Mary Magdalena was associated with Christ, would have allowed her to the crucifixion and not apprehended her UNLESS she was his wife, in which case it would have stood for a kind of in-yur-face moment.
