I never understand how people can do something like that and be able to sleep at night!! Seriously, I would feel horrible if I did that to someone!
Considering it has been so long, I would probably just let it go. Should you have to? NO!!! But I think in the longrun it would be best just to live and learn, however the next time that chick wanted something from me I wouldn't be jumping that's for sure! The way I look at it is what goes around comes around....she'll pay for that mistake someday! Good luck
