do you believe in love?????

Some say love is nothing but a fiction, a hope and trust that you cling to for security reasons, a solution for the social need to have someone. At some points it is right. But it's just like saying that friendship is nothing but a social responsibility, and faith is a blind, illogical explanation of something unexplainable. If love is to be treated that way, and so are friendship and faith, then life is nothing but a dry existence, no purpose, no essence, not living at all. I don't want to see life that way. So I believe in love.
