I want to bite my wife's fingers off when she attacked me
Why would you want to bite your wife's fingers off?
I was trying to defend myself.
If your wife is attacking you, she should receive some help for her anger issues. See a marriage counselor and find out what you can do to live peacefully together.
She does have anger issues. I just don't like her. I let her do whatever she wants to me.
Both of you seem to have difficult personal problems in this relationship. Seek out counseling to sit down and talk through your troubles. Your wife shouldn't be assaulting you and you shouldn't let others trample over you.
