Dear Steve and Shirley, One of my sister's best friends has been dating a man for ten years and he hasn't proposed to her yet, but he's cheated on her several times. He swore that he would never cheat on her again and he joined her church to gain her trust back so she wouldn't leave him. She's still with him and she started to suspect he was cheating again after he turned his phone off her few times while he was out at night. My sister had a brilliant idea that was supposed to help her friend out.............................................
