I have this friend?

Just ignore her and dont return the calls and within a week or so she will get the hint. Sometimes people are oblivious in life and do not see the writing on the wall and sometimes its not your responsibility to set them straight. While annoying it doesnt sound like if you confronted her she would take it nicely and you will wish you just ignored her to begin with. Why subject yourself to a drama queen? Just ignore her and she will get the picture without it bruising her ego and her lashing out at you. Dodge her and ignore her.
