I actually am in the camp that thinks Lureen loved Jack. ... But the fact that she suggests that he go to Lightning Flat is *huge*, especially considering that in the short story we learn that Jack never once took her up there to meet them. The unselfishness of that gesture is astonishing, and to me it has to be borne from love.
Hey Barb, we definitely agree on this!

I’ve read on other boards that Jack’s was an unrequited love; I respectfully disagree.
Wow. I find that idea -- that Jack's love was unrequired -- so ridiculous that I would have trouble being respectful of it! Whoops, I guess I just wasn't. Sorry if anyone actually believes this absurdity. Whoops again.

Kidding, and I truly am sorry if there's anyone out there I offended.

There is room for all opinions here, and as moderator I must set a better example of acceptance. But really, to me the plot doesn't make sense on those terms.
I'm willing to debate the notion that Ennis doesn't know he loves Jack, or doesn't think of his feelings as love (I happen to disagree with these views, too, but I can understand someone having them). But to say that Ennis flat out doesn't love Jack at all? That's hard to picture. As you point out, Barbara, why would Ennis bother with the relationship at all, then?
