urgent!! ask help suggestion

A white female lab worker, white trash, nearly 50 years old called me several times "pretty boy" and even phoned me wanted me fuck with her. I suspect she has some psychical problems. She is alone whole life and always complain that she could not sleep, she use my computer in my lab to browse porn websites, adultfriendfinder such website, and match.com everyday.

After I rejected her several times, she get angry. Now, someother things make her feel very intenstion, she suddently threaten me she will report me 'sexual harrassment' if I dont listen to her. Since I just get married, she threaten to also tell my wife.
