Love or Misery?

Currently reading Short Story Masterpieces by 5 British Masters, Oscar Wilde, Hector Hugo Munro, D.H.Lawrence, Joseph Conrad and Charles Dickens. Just completed couple of stories by Oscar Wilde, short, very simple but conveying a strong message at the same time.

From one of his stories, The Model Millionaire, loved this part, kind of funny.

"Unless one is wealthy there is no use being a charming fellow. Romance is the privilege of the rich, not the profession of the unemployed. The poor should be practical and prosaic. It is better to have a permanent income than to be fascinating. These are the great truths of modern life which Hughie Erskine never realized. Poor Hughie! ........ He had tried everything.......Ultimately he became nothing, a delightful, ineffectual young man with a perfect profile and no profession.
To make matters worse, he was in love."

I wonder, why does love always add to your misery?
