My experience is that when you partner won't let you meet or be around this so-call friend. I was always suspicious of this guy because she would talk about him off and on and hang out with him. I guess I was really naive but I had no reason to not believe her. I thought it was me just being jealous, nope. It was all a lie. She didn't want me to meet him b/c she was lying to him about having a boyfriend.
