I guess I have not been involved in this discussion from the beginning but I'll try to add to this. The reason she called you was because you were the first person she thought of and she feels comfortable to call in such a situation. She called you on as a friend, because friends help friends out in time of need. I dont think there is anything more there. If you feel that you want to help her, then you should. You can give her attitude while you help since she deserves it, but not too much. Just cold-shoulder her, but help her with the situation. If you are truly pissed off at her, then dont bother, dont even call back. In the past you been coming to her, now she is coming to you, make yourself a bit unavalaible, but dont let her know. Maybe if you become a challenge, she might become a bit more interested.
