Hi
I don't take offence to your remarks as I wonder if that is how you feel about yourself or maybe how you think your wife felt about you at the time?
I can empathise with how you felt when you posted this as it is very similar to how I felt when I was assaulted by my drunken boyfriend in a past relationship. I felt sick, frightened, shocked and couldn't quite believe what happened. I also felt weak and vulnerable.
You say you have been married for 10 yrs yet the abuse has only been in the last 3 years, has anything happened that could explain this?
I am sure your wife does love you, but needs to understand that she cannot continue abusing you. In the last 3 times she physically abused you was there a trigger or a pattern??
Unfortunately my ex used to tell me it was my fault too. I don't care how angry someone makes you, you can always walk away. It was her choice to hit you. Here is a link you may find useful

I really hope that you and your wife can resolve things.
