Though not a Romantic lah-de-dah outcome, I still find Paint Your Wagon to be an entertaining view as well as a nice intro to the problems of making a real-world vee (& some small hope that it might be workable).
There's Dirty Rotten Scoundrels, where the two main characters vye to scam a tourist, & wind up as buddies (albeit still competetive). The ending still makes me laugh, & I've always felt a bit disappointed where there's never been a sequel to explore how the relationship might have evolved. Anyway, it's a remake of Bedtime Story, & in turn is being remade as The Hustle (but with two women in the lead roles, thus apparently playing to the standard FMF fantasy).
