Romeo and Juliet perdiction

I think that Romeo and Juliet will die, one because Romeo said that exile is worse than death, so I think that because of that and because he is implosive, he will make a rash decision, so he doesn't have to live without Juliet, instead die. Than I think that Juliet will be super sad because of that and she will decide that if she dies that she can possibly be with Romeo because she loves him so much, so she'll just kill herself.
