How does Shakespeare explore the themes of love in Romeo and Juliet?

Although Romeo and Juliet is considered one of the world's greatest love stories, it can be argued that the love story is only a vehicle for the resolution of the story about hate, that is, the feud between the two families. After all, the story starts with a street fight between Montague and Capulet servants and ends with a peace agreement between the two lords. The power of hate is illustrated in the first scene by the exhibition of enmity between servants of the two families. The extent of the hatred has grown from the family itself to its servants. The power of love is seen, of course, in the determination of Romeo and Juliet to defy their families and be together. They love their parents, but the hate between the families causes the young couple to hate those who would keep them apart. The passion of Tybalt's hate is seen in his inability to forget about the party crashing. Even though his uncle talks him out of a fight that night, the next morning he sends a challenge to Romeo's house. Romeo's love for Juliet prevents him from quarrelling with Tybalt because he does not want to fight with his beloved's cousin, who has become his cousin by marriage. But his love for his friend Mercutio is powerful enough to turn into a rage of hateful revenge, so Romeo attacks Tybalt for killing Mercutio. For Juliet, the death of her cousin is a test of her love for Romeo. Which is stronger: her love for her family or for Romeo? As it turns out, her love for Romeo is strong enough to allow her to forgive him for his terrible deed, to choose her family by marriage, her husband, over her blood family. Juliet's love is further tested when she has to overcome her doubts about the trustworthiness of Friar Laurence and her fear of taking the potion. Again, her love is strong enough to risk everything. Romeo's love is strong enough to risk the Prince's punishment to get to Juliet's tomb. Both have love strong enough to be willing to die for the other, and they do. Thus, the whole play is a clash of passionate love and passionate hate, each strong enough to cause tragedy.
