Urgent: How to handle this situation

Hahaha, what a funny woman, but the good thing is you finally got to tell (or give hints) others about your side of the story too ;-)

And Sweety, since you know what sort of person she is and since you are not comfortable with her, please do try to limit yourself from her in future. You don't really have to help every single person who comes seeking something from you. And a person like this girl- well, she has shown many times why she doesn't deserve your help, so just keep things on the professional level with her from now on and be happy with your own set of friends.
