Jo, Stay strong and do what you have to with the law. Your XH wants to apologise because he is afraid of getting in trouble. I am also afraid that his anger will grow, so make sure you are protected by the law. I didn't become half that angry when I found out W, slept with OM last summer. (I actually told her that God would forgive her if she would ask honestly for forgiveness. He over reacted in a major fashion which is not normal.
