What are the sacrifices Romeo and Juliet have made in order to be together?William Shakespeare's Romeo and Juliet

Certainly, Romeo and Juliet both sacrifice much in their
daring and "star-crossed" love.  For, they both abandon the safety and security that
comes from being children of aristocrats in Renaissance Verona, Italy. Their impassioned
love drives them to risk death on more than one
occasion.

Indeed, by attending the masquerade held in honor
of Juliet, Romeo challenges the edict of the Prince, who in the first scene of the play
forbids the Montagues and Capulets to disturb the "quiet of our streets" under pain of
losing their lives.  For, by entering the Capulet home, Romeo risks death at the hands
of the fiery-tempered Tybalt, who identifies him.  Later, in the second scene of Act II,
Romeo scales the walls of the Capulet orchard in the hope of again seeing Juliet; in so
doing, he risks death if any of the Capulet servants notice him.  When she walks out
onto the balcony, Juliet tells Romeo,

How cam'st thou hither, tell me, and wherefore?

The orchard walls are high and hard to climb,
And the place death,
considering who thou art,
If any of my kinsmen find thee here.
(2.2.66-69)

Their subsequent
pledge of love and hasty marriage also endanger the young lovers.  For, Romeo and Juliet
have clearly sacrificed their security within their own families, and they both have
risked the wrath of both of their families by this marriage. 

In Act III, therefore, the danger of their having married
their enemies presents itself as Tybalt and Mercutio argue and the newly married Romeo
attempts to intervene.  Pledging his love for Tybalt now as the in-law of the Capulets,
Romeo raises the ire of Tybalt who is ignorant of this new development; he raises his
sword and Romeo impedes Mercutio from defending himself.  This tragic action causes
Romeo then to be banished from Verona by the Prince.  Thus, by marrying Juliet, Romeo
has lost his very citizenship in the Verona community and must separate himself from his
new wife.  So, he has to sacrifice any comforts he might have as the husband of
Juliet.

With Romeo banished, Juliet finds herself in a
situation which calls for self-sacrifice.  Since she cannot be with Romeo, her new
husband, and she cannot marry the Prince as her mother and father desire, Juliet loses
the security of her earlier life and must sacrifice her safety and comfort.  She turns
to Friar Laurence and drinks his potion to forestall any marriage between her and the
Prince.  With this potion, the friar plans, she will sleep as though dead; meanwhile the
friar will talk with Lord and Lady Capulet, informing them that their daughter cannot
marry Paris since she is already married.  However, the plan to notify Romeo in time
goes awry and the two lovers despair; finally, they pay the ultimate sacrifice of their
lives for the love of each other.
