Romeo and Juliet

In the beginning of Romeo and Juliet, Romeo shows his idealism in conventional love. His perception of love is idealized and immature. After he meets with Juliet, however, his understanding changes. He has founded his true, romantic love and he is ready to even risk his life to stay with his lover.
Before Romeo falls in love with Juliet, he idealizes his love with Rosaline, who possesses chastity and Dian’s wit. He focuses only on his subjective experiences, therefore he is indeed in love with the notion of being in love. He is more interested in the grief of being in love. He sees that love adds only grief in his breast and causes the sea to be filled with loving tears. On the other hand, he is aware of his conventional love as well. He says,
Feather of lead, bright smoke, cold fire, sick health,
Still-waking sleep that his not what it is!
This love feel I, that feel no love...
