We've discuss, and it's been written about in various article about wheather Jack and Ennis was gay, bi, straight. These men indeed married, and had children. For twenty years they continued their relationship during the changes in their lives.
We have Alma and Lureen their wives who loved them in their own way, but now Randall is introduced, the dynamics change. Jack we all agree was seeing Randall, knowingly not telling Ennis, but wisely holding that information back, but telling Ennis in so many words, he wasn't exactly deprived himself sexually which forced Ennis to make that threat to him.
What I'm trying ask if Ennis and Jack could freely talk to each other about the women in their lives, why do you think speaking of another man was apparently off limits?
Why did Jack hedged in what he was willing to tell Ennis at that final confrontation. Why was Ennis so angered to point of violence at the hint of Jack being with someone else?
If woman couldn't come between them, why would another man could be such a threat to them? Do you think either of them understood what was going on between them, the Final Confrontation was kind of a wake up call, would they have found the answer? And Ennis more so than Jack could find some peace in who he was, if he just accepted it at that moment, and give up the struggle of denying himself the truth and a life with Jack?
