<< thanks for all the inputs guys. i was going to help her anyway, but after all this I have a feeling she's only using me. you let her take one step on you, soon enough she'll walk all over you. and btw, i've talked to my current gf (yes, she's officially my gf now) and she said I should help her too.. but left it up to me to make the decision. >>
Talking to your current g/f about this was probably the best thing you could do. This is a tough situation because we really don't have enough information to make an educated decision (we need to get a feel for the emotional nuances involved, and verification that your ex has no ulterior motives). As for your "neutral mutual friends" who now think you're a jerk... I wouldn't give them a second thought.
