Thank you Welshwitch and CrimsonSky,
In the tent that second night, you saw how Ennis lost himself in Jack. He finally found a safe harbor. But that couldn't change the conditioning of so many years prior. So when it was time to part at the end of that summer, we saw Ennis reaction when Jack's truck past him on the road. He felt something rip at his insides, and how he tried to fight it. And fight it ever since then.
You're right subconsciously he tried to push Jack away, not really wanting to, but that was how its always been for him, people just up and leave out of his life, why should Jack be any different, "look, I'm giving you a way out of this."
Jack always wanted Ennis to be the one who made the first move in being together, and tauted him about Mexico, and on a short leash he kept him on, etc. We know how tortured Ennis was. Why do you think knowing this, Jack never gave the hint of him leaving everything and moving closer to Ennis. We've (Well I have been) concentrating on what Ennis role in this back and forth game, why didn't Jack make any declaration of him giving up what he had to move nearer to Ennis? The more I read yours and other post on this subject, I'm beginning to wonder who was the one who had the real power in this relationship, and who used it?
Thank you all so much.
