Optom, you are revealing something powerful !!
You say: I also think this is why Ennis fights so physically,he cannot fight the love,he has fallen, desperately and irreversibly.He is trying in the only way he knows to gain some measure of control,hence the physicality that overtakes him both positively(reunion) and negatively,(the many fights,both with Jack and others)
In the film the proof of his love which he believes is about to be lost for ever,is the fight on the mountain before they come down
...........
Optom, may I be surprised by the + and - as you say, and I add too that Ennis uses both in that warm to cold cowboy fight before coming down that mountain; at first, it is positive as Jack warms up to him, but then the force is negative !! So, both, Ennis and Jack then and there are similar: they are BOTH in love SAME TIME !! ??
That is what I think !! What do you and others think ??
Au revoir,
hugs!
