Romeo has matured throughout the play, even though it only spans over a week’s time.  His true maturation is through his notion of love.  In the beginning of the play he pines over his lost love Roseline.  He absorbs himself in verse and locks himself in darkness and seclusion.  He talks to his friends about having the beauty of life sucked out of him because love denied him.  When he meets Juliet, things change.  Many criticize and say that their love was based solely on primordial instinct and desire.  This is true but most “healthy” relationships are based on the same.  The difference now becomes in age.  Granted the two were very young but does that mean they do not know how to love?  The answer is, “no.”  Romeo and Juliet may have been young but by the end of Act V you realize that they loved each other more in that week that some have in a life time.  They may also be teenagers but they both put as much conviction and passion into their relationship as someone twice their age.  Did Romeo mature throughout the play?  Yes, his notion of love and his actions toward the idea made him wise beyond his years.
