Hello, I just got your email address from one of website and I believe you can help me to resolve the problem. nMy father is in extra marital affair and today my mother was not at home so he took chance to call her at home when I was also going out of home. But somehow my instinct hold me back and felt father behavior changed he showing care that I am going out which normally never showed up. nAnd came out of the home but returned back home within few minutes and found she was entering and then only I decided to sort out the issue right now and thereby I caught her entering my home and gave her a tight slap and pushed her out of my home. Hold my father back inside home and yelled on him to come to the conclusion regarding this matter, and surprisingly he told he can't leave her. nThen some extreme 1hour shouting happened. nnBut I want to take either legae Or illegal action regarding this matter. nnKindly it will be very much helpful if you help me to come to an conclusion as my father
