When you love someone deeply, does it hurt?

Or does it make you happy?

What if you found out that you love the other more than the other loves you?

What would you do? 

Is it possible for someone to hate someone and love them at the same time?

Or does the hatred cover the love and turn into evil?

Can the love cover the hate too?

Was there ever hatred for the other? Or was it just hatred for youself?
