My wife is very hot tempered and she like to hit me when she lose her temper. She will dig her fingernail into my skin and sometimes she will slam my head against the wall. I don't want to hit her back. I love her. I believe she loves me too. How can I calm her down. And stop her from abusing me like this.

I'm so sorry to hear that but have you tried to consult a Psychiatrist? Your wife shows that she has an anger management problem. She has no ability to control her actions especially when she is in rage and it is not good to the both of you, especially on your part that you are experiencing domestic violence.
