help me to believe what i know i can't

In English class we have been reading Romeo and Juliet. Along with analyzing the book we have spent some time looking at our own views on love. Are we the type to fall within moments like Romeo? Are we slightly more cautious like Juliet? Are we just looking for a good time like Mercutio? Or are we bitter, and pessimistic like Benvolio? Unfortunately I'm more of a Benvolio than anyone else. When we were sharing our views I began to realize that I not only hated the idea of one person being made for you, but I don't believe that the human mind is capable of actually loving. Isn't love supposed to be someone putting their partner before everything else? No one does that. I just can't see myself only being made for one other person. You have to be made for multiple people because what if you miss out on that supposed one person? Then everything is over? No. Some say that they live for love, but would they die for it? It just doesn't make any sense to me. In class we all joke around about my negative opinion, and I put a smile on, but I worry. What if I'm the only person in the world who's not capable of love? Forever in like, Sydney
