Get help

To clarify, so that the original poster doesn't let himself believe that I'm on a femme-rant, I attacked my soon-to-be-ex in a violent rage after finding out that he had been engaging in horrific extra-marital sexua| activities and interests that were so repulsive that they caused me to be nauseous.  The attack came after six weeks of "talking" with him and directly asking him if he'd been with other people - which he denied.  I am not proud of my actions, nor will I excuse them.  I got help, immediately, and he went on to press charges, only to dismiss them.  Before this incident, there had never been a moment of violence during our entire marriage.

Now....to get to the original poster, and it's harsh.  Young man, you and your former girlfriend are in dire need of some intervention.  You claim that you beat her from 2am until 6am while she screamed.  No amount of alcohol can excuse 2 hours of torturous beatings.  Get some frigging help for yourself before you kill someone and then whine about why you're in prison for the rest of your life. 

NEITHER of you have any business drinking.  Period.  And, you set HER up by buying more alcohol when you stated that she was clearly already drunk.  No business drinking, and no business dating another human being until you both sort yourselves out, individually.  She is not the reason that you behave the way that you choose, just as you are not the reason that she behaves the way that she chooses.  You each have some serious issues that will make for miserable, empty, and violent lives unless you each do something to stop the cycle.  And, since you can only control yourself, I would strongly suggest that you take control of yourself and get the strong help that could save you from a lifetime of misery and/or incarceration.
