How does the suicidal impulse that both Romeo and Juliet exhibit relate to the overall theme of young love?
Does Shakespeare seem to consider self-destructive tendency inextricably connected with love, or is it a separate issue?? Why do you think so? Give Examples of how their love is, isn't, or could be both self-destructive or a separate issue when considering the elements of love.

As a more simple answer to your question, Shakespeare shows that young love is an 'all or nothing' proposition. When Romeo is told by the Friar that his punishment will be banishment, and not death, Romeo replies that there is no world for him outside Verona.
There is also a measure of idealism in their love. Juliet and Romeo refuse to bend to the reality of their family situation, believing that love will conquer all.
I would suggest that Romeo's and Juliet's suicidal impulse comes not just from the "love" part of your description, but mostly from the "young" part. Both Romeo and Juliet are extremely impulsive throughout the play. Romeo is already been pining away for another girl named Rosaline at the beginning of the play, but immediately forgets her the instant he sees Juliet. (The friar even comments on how quickly he changes his affection.) Also, at the beginning of the play, Juliet tells her mother that she's never even dreamed of getting married, but of couse that instantly changes when she sees Romeo. In addition to their natural impulsivity, which we see plenty evidence of in the play before they contemplate suicide, they are too young to have the experience of having a broken heart that's healed over time.
Their love is very strong, powerful enough that they would die for each other without any hesitation when one is down and gone. It shows that their love is too strong that they would do anything for each other, even murdering someone, he would readily do. Their love is too deep that they become doom lovers with doomed love. They love each other even though their two families are feuding rivals. They secretly married each other without anybody consent and allow love to control them blindly, taking them to a place where there is destruction and mayhem happening everywhere and anytime. Their love is too risky to exploit further.
