Great unrequited love

Have you noticed that the majority of love lyrics tell us about unrequited love and even proclaim it to be great? So why does this painful feeling provoke such inspiration?
Very often the poetic lines depict the inner state of authors, their love suffering, personal drama, etc. The energy of unrequited love stimulates the energy of creativity turning it into the high creative potential. Poet and writer didn't have place to express feeling and they directed their feeling to the poems filled with passion, suffering and pain.
And such description of love affairs full of suffering puts the certain example to other people who want to feel the same feeling who want to experience the same emotions and events. And in such case love turns into obsession and unrequited love spreads in the world in the form of pseudo true love.
So, reading a book it is necessary to remember always that love is not only the individual feeling but also the unique one and there are no similar love affairs. Of course there may be similar ones but in the end the tenderest love is your own unique love. Don't forget about it and when your children start to read the lyric poem it may be the next propaganda of love addiction.
Love must be based on positive emotions and feelings. They must bring pleasure and delight instead of suffering and pain.
