Splendor in the Grass(1961)

Deanie (Natalie Wood) suffers a nervous breakdown after the failed romance with Bud (Warren Beatty). She goes to a mental hospital for two years, where, after intense therapy, she returns home, engaged to a man she met at the institution.

She asks her friends to see Bud upon her return. She is surprised to see the once-wealthy Bud living on a ramshackle ranch. Bud introduces Deanie to his wife and young son. Deanie and Bud have a bittersweet conversation before Deanie leaves, saddened but no longer broken in spirit about her youthful love affair.
