Casablanca (1942)

Ilsa: I can't fight it anymore. I ran away from you once. I can't do it again. Oh, I don't know what's right any longer. You have to think for both of us. For all of us.

Rick: All right, I will. Here's looking at you, kid.

Ilsa: [smiles] I wish I didn't love you so much.

How happy is the blameless vestal's lot!
The world forgetting, by the world forgot
Eternal sunshine of the spotless mind!
Each pray'r accepted, and each wish resign'd.
