Act III, Scene 5 of Romeo and Juliet shows us a few things about Juliet's relationship with her parents.
The first we see is that Juliet does not trust her mother in the same way that she trusts her nurse. We actually see Juliet lie a few times in this scene. First she lies in allowing her mother to continue to believe that she is weeping over Tybalt's death, and then she allows her mother to believe that she wants to seek revenge for Tybalt's death and that she hates Romeo, even that her "heart abhors / To hear him named."
Another thing we see, is that both parents seem genuinely concerned and heartbroken to see Juliet grieving so much. Lady Capulet begs her daughter to "have done" with weeping, and that, "Some grief shows much of love; / But much of grief shows still some want of wit." Likewise, Lord Capulet describes his daughter as a ship sailing in the tempestuous seas of her tears in the line beginning with: "Thou conterfeit'st a bark, a sea, a wind: / For still thy eyes, which I may call the sea..."
The final thing we see is that Lord Capulet expects a relationship from his daughter that is complete obedience. Likewise, her mother expects Juliet to do as he commands, saying when Juliet refuses to marry Paris, "I would the fool were married to her grave!," in other words, I wish she were dead. Lord Capulet even begins hurling insults at their daughter, telling her to get out. Her mother's final exit lines are "I have done with thee."
Hence, Juliet's relationship with her parents is a very delicate one. She feels no trust in them, nor do they truly care about what she wants. While her parents may argue that a happy wedding day would abate Juliet's grief, the truth is that they are eager to see her in a prestigious marriage.
