I wonder why Jack left so easily in the post-divorce scene. Watching this a few times, it seems like he kind of gave up without a fight. Ennis gives a few lame excuses, the visitation with his girls, etc. and then Jack just say OK see you next month and leaves. After driving all that way to stay for only a few minites? Why not protest right then, or say meet up with you later, something. It seems like his leaving was so abrupt. This was such an awkward and heartbreaking scene. The entire vibe of the movie changes after this.
