FZ gets owned by AAP on a regular basis, but it's usually from behind, so that's nothing special.
from that IM conversation, she seems so emphatic. the truth of where her heart lies is unknown to all of us, possibly including herself. but if she does still have romantic feelings for this other fellow, and knows it...she must be absolutely pathological to be able to say such things to you while still caring for him.
i think you have the right idea, in that you want to know what she wants. if you discovered that she felt more for him than for you, i know you would leave. and that's the only thing to do...scarcely anyone could be worth holding onto in such a situation. chances are, not her.
but it's possible that you may have pushed things a bit a too much, because you've elicited her "no no i love you"-relationship-survival response. maybe it's true, but maybe it's just instinct. you want to go beyond the conscious attitudes and behaviours, and try to see how she thinks, talks, and acts when at her most natural.
it would be nice if you could just ask her what she really wants, and explain that her happiness is the issue here, and that you're not trying to get an apology, or punish her, or make her beg, or control her. but it's entirely plausible that this will only kick up an automatic, defense reflex (as she may have displayed already).
lastly, try to consider the mindset, values, and even past relationships of those who give you specific advice advocating one approach or another. if a dude who doesn't seem to really care for girls, or want long-term relationships, tells you to "dump the fucking bitch and move on"...heed his words with caution, because he probably doesn't think like you or want what you want.
good luck.
