What would be a good example of how romeo and juliet's love is tragic(excluding how they die at the end and how they are from separate familes)?

would how people(friar, nurse, capulet, mercutio, ect.) doubt the two being in love count as being tragic?

Well for one I think their immaturity didn't help the situation.  Their love was a lot like puppy love in the sense that it was their first time dealing with a relationship and therefore didn't know how to handle issues that were thrown at them.  At the same time, some of the other characters may disagree because "young love is the best love" in the sense that it is pure and innocent.
