Romeo Character synthesis

To me Romeo is very unique character.  He can literally turn his mind from off and on like a switch he is very unpredictable, for example when he was in love with Rosaline he changed his mind to Juliet in a matter of minutes, “Guest list… My fair niece Rosaline and Livia,  And those who often drowned, could never die… be burnt for liars on fairer than my love”  (Shakespeare 46-48).  Like in the quote he just changes to Juliet as soon as he lays eyes on her.  “Then move not,while my prayer’s effect I take.  Thus from my lips (Romeo to Juliet) Juliet-Then have my lips the sin that they took”(Shakespeare 72).  He is a pretty chill dude but he is no stranger when it comes to love,  I mean he will do anything to hook up with someone he is in love with and i mean any one he will even break someone’s heart for another man of woman he is in love with,  he is very unpredictable as well i mean he almost himself for Rosaline and then he just turn one of his switch on in his brain and said Juliet is the one its like he backs up on what he said.
