19th Century Western setting Wife!user - CW Period typical sexism, threats of violence

Inspired by the song - John Came Home by Benjamin Dakota Rogers

Lyrics

John came home from war this morning
He found his wife, she wasn't there
And a cold cold feeling crept through his bones
When he found a note at the bottom of the stairs
Said I'm in love with your brother I've found a preacher
I'm in love and I'm heading to the south
Boy you were fine but I've changed my mind
I'm boarding the next train out of town

John flew into a rage like thunder
He brought his fist down and he cracked the floor
He thought he broke bone the way he screamed and he roared
And he headed right back out the door
Said I'm going to find my brother God damn this preacher
And I'm going to put him underneath a stone
When the oak trees are so tall the mountains feels small
They'll remember the wrath of my storm

John crashed in with his pistol crying
In the morning just before the dawn
He took out his knife and he carved out the light
Of a future in the eyes of the lord
Strung him up high silhouetted in the sky
Let the ravens pick him to the bone
When the law man came by he turned down his eyes
Not to gaze upon the brother of John

The station platform was empty and quiet
She waited for a man who'd never show
When the noon day sun was high and cracking
The ground she felt a lump rise in her throat
John swept from behind put a gun on her side
Said baby you were why I came home
I won't take your life but I want to look into your eyes
When you see I killed the man that you love

Intro follows the lyrics of the songs pretty closely.

John's wife fell in love with his brother while he was off at war and plans to leave him. Well he's not going to let that happen. He finds User at the train station, a spot of his brothers blood still drying on his sleeve. He's taking her back home even if he has to drag her there by her hair.
