In “For Love or Money,” a second-season “Dallas” episode, Cliff (Ken Kercheval) meets Sue Ellen (Linda Gray) in a park, where he ends their relationship.
SUE ELLEN: I thought you loved me.
CLIFF: I do, I do – in my own way. It’s just that J.R. made me realize that there are things that I need – and I can’t have them and you.
SUE ELLEN: And would it be so bad just to have me?
CLIFF: Look, if it stopped me from getting them, it would, because I might not ever be able to forgive myself – or you – for what our relationship might cost me.
SUE ELLEN: And what about what it would cost me?
CLIFF: Look, I can’t explain it. J.R. just pushes certain buttons and maybe I’ve got to learn to play the other man’s game.
SUE ELLEN: So that’s what it is? Just a game?
SUE ELLEN: The winner takes the marbles and goes home? Is that what I am? Just the marbles?
CLIFF: Look, I’m sorry.
SUE ELLEN: You’re sorry? [Voice breaks] Yeah, so am I. You’ll never know how sorry.
