Quite ashamed about this one.
When I was 18/19 I was with my then girlfriend of about 3 years. We were having a blazing row and she went too far.
She made a comment along the lines of "your loser father couldn't keep a relationship together and you can't either!". When I was around 11, my parents got divorced and fought for custody. My dad wanted me and my brother because he genuinely loved us. My mum wanted custody just to spite my dad. She won, and my dad lost it over the years.
This was too far for me. I had never, EVER hit a girl before, but it happened so fast I didn't even know I did it.
Basically, I cocked my fist back, and flew it straight into her nose. I thought it would be like the movies where she would get a little trickle of blood. It wasn't... her nose EXPLODED. I think I must have broken a bunch of cartilage or something because blood shot out of both her nostrils, got all over me, got all over the floor. She staggered backwards, hit her head hard enough on the wall to leave a dent, and slumped down.
We were both stunned for about 10 seconds before she started crying hysterically and ran into my room and locked the door.
So I went to wash my hands, and while I was in the bathroom I heard her run out of the house and take off in her car. So later I went home and broke down in tears.. My mum came in the room and when she heard about the story she got scared and said your moving with your auntie and uncle in bel air. I whistled for a cab and when it came near the license plate said fresh and had dice in the mirror. If anything I can say this cab is rare, but I thought 'now forget it' - 'yo homes, to Bel Air.
