I am doing research on the different out comes a abusive marriage can result into.

For one
Jail time
2
she remains in fear and resentment=marriage ends up dysfunctional
3
divorce

I hit my wife once, when we were 19. The second time I went for her, she grabbed the phone and clobbered me on the forehead. After we went to the hospital for 8 or 9 stitches, the Police would not give us a ride back home. We couldn't afford a cab, so we had to walk.

Guess what, we decided that hitting each other was pointless. That was the start of our education on fighting fair.
