I think Romeo and Juliet's reactions are very similar. When Juliet first found out, she was angry at Romeo for killing Tybalt. In Act 2, Scene 2, line 75, Juliet says "Beautiful tyrant! fiend Angelica's!", saying that such a beautiful thing like Romeo is so terrible for murdering. However, later in line 95, she says "O, what a beast was I to chide at him!" saying that she regrets her anger. After this she proclaims how she is only sad at how she can not see him due to his banishment. She is thankful for Romeo killin instead of being killed.
When Romeo finds out, he is upset that he can not see Juliet. He is not as thankful for his life like Juliet was for it.  Friar Lawrence got angry at him about this and told him to be thankful for his life.
Both missed each other greatly and were upset they couldn't see each other, However, Romeo was not thankful for his life and Juliet was.
