If Jesus and Mary were an item or married, why would they be surprised that Jesus spoke privately with his own wife?
Were they jealous of Jesus' wife? Doubtful. I would imagine that after their savior died, they would do everything they could to care for the woman he loved.
There is nothing that is for sure because crucial pieces of the text are missing.
I believe it's unwise to play an assumption, guessing game about missing pieces.
