The bible doesn't say anything specific about what happened to her after the ressurection of Jesus. If it were important that we know, the bible would have told us. She was just a disciple, a faithful companion like the rest, and to speculate that she had a relationship with Jesus beyond what the scriptures tell us is useless. Conspiracy theories abound, and there is no end to the stories. Jesus was what the bible says he was, the Son of God, our king and redeemer.
