Have you ever been talking to your wife/gf on the phone and sensed, or knew, that she was having sex with someone while you were talking to her? What exactly was it that made you think or question whether she could be? Also, have you ever heard anything in the background after you thought you were hanging up, but discovered that she didn’t end the call on her end? The same thing goes for if she’s called and left a voicemail, and again, she forgot to end the call, so you were able to listen to what was going on, or being said. My ex fiancé, Robin had done that on several occasions as had another ex. I’ll share my stories when I have more time, and if there’s enough interest about this topic.
