Romeo and Juliet - Prediction

What happened between the families at the end of the play?

I think the family's should have ended their ongoing fight because of this tragedy. They may have realised how they have acted had affected thier children and that it should come to an end.
Although this may have made the feud worse! They could have blamed each other and made matters worse.

What if Romeo did not die but Juliet did?

If Juliet really died first I think Romeo would have still gone through and killed himslef as well. Romeo loved her so much and he probably would do anything for her. If he didn't die he probably wouldn't have fallen in love again and ended his life later on.
