falling in love...

falling in love is like a rollercoaster- it has its ups and downs, its highs and lows. But for the most part, it is the feeling of exhiliration that is most intoxicating. It's excruciating, it's bitter sweet. Like you're high on drugs-- when the feeling is over, you are hit with the reality-- with a thud! And you're landed in a heap, feeling sorry for yourself. And yet, why do people keep falling in love? How would you differentiate loving someone and falling in love with someone? Is there a difference between love and possession? Can you love someone without possessing them or can you possess someone without loving them?
