I don't think Jack would quit Ennis just like that. He loves him too much. Jack would, however, try to find a new life if things were not changed. I think Jack did think about quitting Ennis on the final meeting when he thought about the happiest time he had with Ennis--the Dozy Embrace. I'm a beleiver in hope, so I think Ennis was making progress by sending the last postcard. So in the November meeting, if Jack didn't die, things would change--a little. Ennis takes small steps.
