Sleeping with Other People (2015)

Can two serial cheaters get a second chance at love? After a one-night stand in college, New Yorkers Lainey and Jake meet by chance twelve years later and discover they each have the same problem: because of their monogamy-challenged ways, neither can maintain a relationship. Determined to stay friends despite their mutual attraction, they make a pact to keep it platonic, a deal that proves easier said than done.
