I need a legal avice from you.
I got in to an extramartial affair with a lady (common friend's wife).We were initially chatting in Whatsapp and later we met at her place. But this lasted only for 4-5 months. We never met outside except once in a nearby restaurant during the day time. Last month I confessed it to my wife and my in-laws including my family members. Since then the lady has been harrassing us making continuous calls and messages. She even went to my in-laws and told very nasty things about me. Now she is telling me her husband will file Sec. 497 adultery case against me. She is threatening me that she will produce the whatsapp chat history or do something to herself.
What precautionary measure should I take now? More than the case I am worried about my wife and daughter who are in to a trauma of getting calls and messages from the lady.
