Sorry to bump up a thread that hasn't been commented on for a while, but I just thought I should reply to this one. I believe that Ennis and Jack would have told their children the same thing. With Ennis, we pretty much see him doing just that in the movie. When he tells Junior "Does he love you?", we can tell what he really means by that question. I can imagine Ennis in the years ahead having conversations with his daughters and them coming to him for advice, and he, now wiser and more reflective from his experiences would tell them to always listen to their hearts, and never let anything else get in the way. I believe Jack would do the same, he never regretted loving Ennis in the slightest no matter how much pain it caused him over the years that Ennis wouldn't listen to him and kept them apart for all that time. Jack would never ever give up on Ennis, and he not died, he would have continued trying to get Ennis to listen to him. While the hope that Ennis would finally listen to him did diminish after twenty years, it could never completely go away. I believe in the end if we were to ask Jack was it worth it to love Ennis this much, and was it worth going through the pain of not being able to be with him, what would you rather have, Ennis and that pain of being part, or having never met Ennis at all? And Jack's answer would be definitely be that it was worth it, and that he could never imagine going through this life and not meeting Ennis. Jack loved Ennis for he was, loved everything about him, and although he was frustrated at Ennis's fear, he wouldn't want to change anything else about Ennis, he only wanted to make Ennis realize that he needs to just listen to his heart, and we all know in the end, he makes Ennis finally realize this and learn that lesson, even though tragically, it was too late for Ennis to tell Jack in this life. So Jack's advice would be to never settle for anything less than true love, and that true love is definitely worth it. And never give up on it, because true love transcends everything.
