Romeo's impulsive behavior

Romeo is an impulsive person, because when he saw Rosaline he said it was love at first sight, and then he saw Juliet and was completely over Rosaline.  He goes for what he wants, even if he has to break the rules.  Romeo says, “Then move not, while my prayer’s effect I take thus from my lips, by thine, my sin is purged (act one scene 5).”  This shows that Romeo went for Juliet, because he knew she was the one, and that same night they kissed, love struck.  Also, Juliet says, “Thy purpose marriage, send me word tomorrow (act two scene 2).”  This shows that Juliet wanted to marry Romeo and his impulsiveness payed off.  Clearly, Romeo is a very impulse man.  He has shown it threw his love to Juliet.
