Dear Arie1276,
Sorry to hear about your experience. I also had gone through such a situation. It hurts sometimes but i learned that one person can hurt you once or twice afterwards we also learn from the experience. I would suggest you be what you are and help her when she seeks your help. You are not doing it for her but for your happiness because as humans its a basic courtesy to help some one who looks like a human in a diffcult situtation or despair. God bless you. Good week ahead.
Regards, Jayakrishnan, India.
