Dear HiAltShag:
You totally flipped the question, giving it another meaning altogether, "THAT IS SO GREAT!!!!!".
To love Ennis, to truly love him, you do have to understand him and his limitations, his needs, his fears.
Remember when he told Jack when they were on Brokeback, about his life, Jack said remarked "That's more words you spoke in the past two weeks" when Ennis replied, "Hell, that's the most I've said in a year." Think about that.
What in the heck did he talk to Alma about? Did she ever talked about his goals, his dreams? Did she really know the man she loved, or was he just the man she was going to marry?
She knew how limited he was in education, did she understand that might have affected how he might have seen himself, and try assure him that he's better man then what he thinks he is?
Did she understand how limited he was in expressing his thoughts, his feeling didn't she just listen to him, and help build that confidence that let him know, the words may not be Shakespeare, but she understood them.
Did she understand the expressions on face and what they meant?
Did she show him how to make love, and not just have sex?
Did she ever tell him you don't ask if your kids want a push on a swing, but you go up and just push them.
Did she make him the priority in her life, show him that he is and most importantly make him believe it ? No, she didn't.
On this I agree with you. May be if she did love him, honestly, with open eyes, and an open heart, what could have been the possibilities?
I have another question, Do you think Jack saw the real Ennis, or was he too projecting his needs on him also?
PS: When I call you friend, I mean it in the best sense of the word, I hope we can be friends.
