Learning to love 'love'

Does anything called true love really exist? Don't we conveniently disguise our desire as love? How do you decide that a particular person is your prince charming, so that you allow him to sweep you off your feet?(romantic, eh?)Man! I am(was rather) dead practical. I read a book called 'Eleven Minutes' by Paulo Coelho and it has changed my perception of love by a fraction.(I am not fully convinced yet). Though the book is very explicit, it took to me a different world altogether. According to the book man was first a bisexual animal with a different set of sexual organs, with 2 faces and walking on four legs. The animal was sturdy, intelligent and was easily a threat to other living beings as it was independent. Hence to weaken this being the Greek Gods cut the animal into 2 parts and that's how man and woman were born. So one's true love is the other half of your body which exists somewhere in the world. This is only a myth. I wonder, when a husband beats up or insults his wife or vice-a-versa, are they really with their lost halves? Was or is the marriage a total mismatch. My friend once said that when he saw a boy and girl hand in hand, he thought there was a story. The story is not like the one above. It is story of their past, present and future. This story goes beyond physical desires. It is about being there when your soulmate needs you the most. This story does not require words. It is conveyed through the language of eyes- the language of concern, the language of tears. The book says and I quote,'Desire of the soul and not the body is true love.' That's the most apt definition of love, I have ever come across.
