How did Mary know after the Annunciation that she would be accepted as wife by Joseph?

Luke 1:26-38 gives us the full text of conversation that took place between Blessed Virgin Mary and Angel Gabriel . The Angel does explain to Mary how she would conceive of the Holy Spirit, but does not assure her of the patronage of Joseph , her would-be husband. We also see in Mtt 1: 18-19 (NRSVCE) how Joseph was on the verge of abandoning Mary in private: >This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit. Because Joseph her husband was faithful to the law, and yet did not want to expose her to public disgrace, he had in mind to divorce her quietly. Now, during the Annunciation which preceded the Vision to Joseph, Mary would have naturally been worried about the prospects of her acceptance by Joseph who had not yet taken her home . One wonders if single-motherhood was socially acceptable in those days. Mary, therefore, would have expressed her fear to the Angel, of her chances of loosing the patronage of Joseph . But we find no such discussion in the Gospels. My question therefore is: According to Catholic Church, are there any apocryphal writings which narrate the discussion between Blessed Virgin Mary and the Angel, on how she would be accepted as wife by Joseph.
