The best way to answer this question is by examining the text from Romeo's monologue to Friar Lawerance.At first Romeo reasons that there is no life for him outside of Verona. In his words, there is only "purgatory, torture, hell itself". Thus he reasons that exile is essentially a death sentence, just a more torturous one.Romeo then expands on why there is no life for him outside of Verona. He explains that everything which lives in Verona may look upon and revel, in Juliet's presence. Romeo explains that he is no longer free to do so, and knowing that would make every moment of the rest of his life a living hell.Simply put; Romeo feels that he would rather die, than live the remainer of his life without Juliet.
