Well, i can say i am in the same boat as you . so you are not alone.
I am also a huge guy (6'2" tall, 225lbs) and my wife has attacked me first with a cork screw, (which i survived a very close shot to the neck) and then with a knife a couple of years later. (didnt connect, thank god)
That lead to me leaving and not going back, the divorce goes thru in feb. Just because you are a man doesnt mean you cant be abused, threatened, and fear for your life also.
Everything your wife did, mine did the same. Put downs, with holding emotions, with holding sex as a weapon and control measure, getting out of control angry over small things.
In the end mine will not deal with the issues confronting us, she is completely justified in what she did, accordign to her. But violence in a relationship cant be excused. Neither can verbal and emotional abuse.
As a BP person i am also extremely sensitive to emotions, however since i have left her, hard as it was, i am so much happier. Not cause i am out whoring around (as she thinks), but because i now have better control over my BP since i dont have to live up to the unrealistic expectactions of life that she has.
You will need to make some seriopus choices soon, but it all starts with her also getting help. If she wont, you need to get out and get out quickly, it will only get worse.
I waited 11 years hoping things would get better. They didnt.
