FC,
I'm a little confused about your recent post. Do you actually have feelings for this woman or not? Is it a pride thing as to who dumps who, or do you actually care about her and the potential for a relationship?
I guess I go back to what I wrote on page one of this thread--if two people in a relationship who care about each other can't communicate about their feelings, desires, hopes, dreams, etc., there is not a lot of hope for a future. If her feelings about the relationship had changed, but she couldn't talk to you about that--what does that say about you, how she can relate to you, how she thinks you would react, etc. I'm not saying that my opinions of her have necessarily changed, but you seem to be questioning your evaluation of the situation and that maybe you weren't being fair.
I think that her looking for a possible replacement while continuing the relationship with you, is a crumby thing to do, but I don't think all that uncommon. It sounded like the two of you did not invest a lot in the relationship from the beginning--so I see the potential for game playing to be fairly high. I guess you need to figure out how you really feel about her and then deal with the situation directly, rather than using a go-between with the he said/she said (I realize she is the one doing that, but you don't need to feed into it). That is pretty middle schoolish imo.
