I think this is what you are talking about. From the screenplay with stage directions:
JACK I'm not you. I can't make it on a couple of high-altitude f***s one or twice a year.
(pause)
You're too much for me, Ennis, you son of a whoreson bitch.
(pause)
I wish I knew how to quit you.
WE PULL BACK NOW
Like vast close of steam from thermal springs in winter, the years of things unsaid and now unsayable--admissions, declaration, shames, guilts, fears--rise around them.
ENNIS stands as if heartshot, face gray and deep lined. Fights a silent battle, grimaces.
ENNIS Then why don't you?! Why don't you let me be? It's because of you Jack, that I'm like this. I'm nothin. I'm nowhere.
JACK starts toward him, but ENNIS jerks away.
ENNIS (CONT'D) Get the f*** off me!
JACK moves toward him again, and this time ENNIS doesn't resist.
JACK Come here...it's all right. It's all right...damn you, Ennis.
And then...they hug one another, a fierce, desperate embrace--managing to torque things almost to where they have been, for that they've just said is no news: as always, nothing ended, nothing begun, nothing resolved.
