The Friar, after they had died.
The Friar told everyone after Romeo and Juliet were dead.
Only Romeo, Juliet, the Friar, the Nurse, and Balthazar knew that Romeo and Juliet were married. None of them told anyone else, even when provoked, so naturally everyone else was oblivious to the marriage.
The quote is from Shakespeare's play "Romeo and Juliet." Romeo and Juliet's families were feuding with other. Romeo and Juliet were in love but due to the families' feud had no chance of gaining consent to their marriage, so married clandestinely. Due to a series of mix-ups Romeo and Juliet each thought the other was dead and committed suicide. At the end of the play their parents are more or less told words to the effect of "See what your feuding has come to," and exhorted to give up feuding with each other.
Romeo is Juliet's lover. He is, as is obvious, one of the two main characters of the story. The basic storyline goes that Romeo and Juliet's families are enemies, but Romeo and Juliet fall in love, get married secretly, then Romeo gets exiled because he killed Juliet's cousin, then Juliet wants to be with him so she fakes her death, but Romeo doesn't get told it's fake and rushes back to where they live, and they both die.
the interview was very straight forward. romeo told Juliet's nurse that he wants to marry Juliet and he told he that if Juliet really loved him she would agree to it.
Juliet's nurse
The Nurse and Friar Lawrence knew about it before anyone else because the Friar performed the marriage and the Nurse was Juliet's close confidant so she told her everything.
If Friar Laurence had told Lord Capulet about Romeo and Juliet's intention to marry, Lord Capulet may have been angered and refused to allow the marriage, leading to potential conflict between the families. Additionally, the rushed decision to have the secret marriage may not have been made, potentially preventing the tragic events that followed.
Juliet reveals her private thoughts that she would not have told romeo to his face
Lady Capulet wanted Juliet to seriously consider marriage, and that Juliet was already older than Lady Capulet was when she got married.
If you are referring to the letter Friar Lawrence gave to Friar John to send to Romeo, then it contained all the information about Juliet's death and what was really going on. It told Romeo to come to the Capulet Morgue (or whatever it's called) and meet him for the awakening of Juliet.
Balthasar told romeo about juliet's death.
