Addicted to Love 1997
Directed by Griffin Dunne | Starring: Meg Ryan, Matthew Broderick, Kelly Preston, Tchéky Karyo
Good-natured astronomer Sam is devastated when the love of his life leaves him for a suave Frenchman. He therefore does what every other normal dumpee would do — go to New York and set up home in the abandoned building opposite his ex-girlfriend's apartment, wait until she decides to leave her current lover, and then win her back.
