I have a girlfriend who has lied to me about an old friend. In the beginning of our relationship she told me about him and said that they stopped being friends because he proclaimed his love for her and she didn’t feel the same way. For awhile this was true — she never talked to him or anything and he was never a concern. A few months ago she started talking to him again, and he said that he just wanted to be friends and I was fine with this because I trusted her. It made me a little uncomfortable but nothing too extreme and I told her how I felt and we were fine, no problems.
One day she and her friend came over and she wasn’t feeling well so she was laying down while her friend and I were outside smoking a cigarette. She told me some stuff about my girlfriend that I didn’t ask to hear, but was completely opposite of what my girlfriend had told me. Only one thing she told me turned out to be true (the friend actually didn’t know what she was talking about fully and was just assuming, which she told me before even talking to my girlfriend), the fact that my girlfriend had previously had interest in this old friend and they had dated. And the way they were talking also indicated the same, and they were flirting on top of that. I told her how I felt and said that it makes it harder to trust her, but will try to and she made the decision to quit talking to him because “he was a problem to the relationship”.
