Dear Steve and Shirley, I need your advice but I pray that you are not too stern with me. I am a 31 year old successful and beautiful woman with two children, ages 3 and 1. I am not married, but I am involved with a married man. It’s my sister’s husband. They have been married for 12 years and I started sleeping with her husband 5 years after they were married. My two children are actually his. My sister and my family members have no idea that I’ve been with this man for so long. Years ago, I started lying about dating a guy that lives out of town and I told them that it’s a crazy relationship, so they don’t need to meet him...........
