For example, in 'Romeo and Juliet', the Montagues and the Capulets' feud, which is related to their social standings, makes their love seem impossible at first. Another theme could be cultural or religious differences. If a novel features a love story between two people from different religions that have strict rules against inter - faith relationships, it creates an impossible love situation. Also, fate often plays a role. Sometimes the stars seem to be against the lovers, like in some tragic love stories where external events keep pulling the lovers apart no matter how much they love each other.

'Wuthering Heights' is a prime example of an impossible love story, with Heathcliff and Catherine's love being thwarted by class differences, family rivalries and their own complex personalities.
