Why?

Saying "I love you" hurts, why?
Talking with him awards me tears, why?
Thinkin about love every single seconds gives pain back, why?
Love has the capability of driving me insane, why?

Love gives me the world but once in a while it takes the world away, why?
Love makes me feel perfect but once in a while it makes me feel like an idiot, why?
Love starts to leave its friend named "Caring", why?
Love is true but it almost looses its meaning, why?

However, I still love love, why?
