I think sometimes just the fact that they've thought about someone else is enough to have them doubting their feelings for you. You are in a great position though Brit...and I think it's better that she tells you about it you're willing to listen. I don't know if guys & girls think differently on this one...but I would rather know than not know. Plus, she's probably feeling you out a bit when she talks about it. To see your reaction.
Absolutely - Someone else can certainly make any issues far more significant, as they almost become an excuse as to why they can leave and pursue another relationship.
I think the best thing I can do right now is listen. Even when I speak a little negatively about him during our conversations, she does agree with me. Whether that is simply to make life simple for herself, or because she really believes it, I don't really know.
