What Is Love?

When you say "I love you" Is that really what you mean? Can you just say you "love" someone Even if you really don't? What does it really mean For someone to "love" you? Is "love" just a word that Can be used without meaning? Is it even worth the hurt For the people you "love"? Could there really be One person that will "love" just me? Why is there even a reason for These feelings inside me? Could there be "love" Even if I am not "loved" back? If there is then why do I feel Like my heart is gone? Even with this feeling Why do I still "love" you?
