Dude, you attacked her with a weapon. You could go to jail for that. Consider marriage counseling. Sounds like the problems are deeper than just the casual disagreement.

You might want to consider anger management classes for the both of you. Also, something to consider is seeing a Psychiatrist (not a psychologist), because there may be some chemical imbalance going on for one of you.

I'm giving this advice seriously. I used to have major anger issues and realized it was manic depression and anxiety. Ever since I've been on the meds, my life has just changed dramatically. My relationships also improved in all aspects of my life (business and otherwise).

It takes a big person to admit they have problems, but an even bigger person to do something about it. Nobody wants to admit they're crazy and going to see a psychiatrist doesn't mean you're crazy. It means you want to deal with any potential problems you may have. Depression affects almost 40 percent of the population, there's nothing wrong with dealing with it. You'd be surprised at how many people around you are taking meds.. Let's put it this way, it can only help and if you're serious about saving your marriage.
