Every Time We Say Goodbye (1986)

This is a unique tale of forbidden love set in Palestine during World War II. 

An American airman serves in the British forces as the Americans had not yet joined the war. He is stationed in North Africa and goes to British controlled Palestine during his leave. He meets and falls in love with a Jewish woman whose family is dead set against the relationship - for several reasons.

The film isn't really shy about even admitting that this relationship isn't really meant to be: he's lonely and homesick, she's fascinated with this foreign character. There is even a side story of their friends who marry and split during the tale. But it seems to be a realistic depiction of war time love as that was the norm as service men left many pregnant women or well-intentioned engagements unfulfilled. 

Nothing beats a good love story though.
