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.

look man.. sometimes wives are behave like this becoz she does not get what she expect from you or her loved one. carefully examine what she really expect from ypu and try to fulfill thise; not you like to do for her. you may love her and you may fulfill all her needs. but i think something is missing. try to find that missing part. your life will be get to normal
