Someone needs to write a Romantic comedy/tragedy where two people fall in love but....

Romantic comedies assume there is a predestined partner who one ends up with after a series of ups and downs and a big showdown. That is not so in real life where everyone just moves on after a while. The fiction of romantic movies can really hurt the expectations of reality. Maybe someday someone researches the effect of chick flicks on the amount of unhappy involuntary singles due to unrealistic expectations.
