When Mercutio is slain by Tybalt and Romeo slays Tybalt, Juliet is initially horrified and thinks very ill of Romeo, which the nurse encourages, but when she has a moment to compose herself, she very definitively takes her husband's side over her family's to the dismay and disapproval of her Nurse.
