Dear LIB readers; my sister is cheating on her husband

From a female LIB reader

My sister is cheating on her husband. She brings the man to the house. My in law is not around, he works overseas (one month in, one month out). He is a nice person and has been taking care of my family and also his wife and their kids. He gives her money a lot and they travel out for vacations, but since this year, my sister has been dating a married man, brings him to the house and cooks for him. Neighbours are noticing. She no longer shows her hubby love. I am scared because if my in law and his family find out about her affair, he will definitely leave her. How do I get her to stop?
