Is it wrong to want or seek vengeance on a girl who did me very dirty?

I had a girl who did me very dirty. Hared me while she was trying to convince me she had a crush on me. Lied to me . had other girls talking about me. Did everything but ask me out and a year later I found out she had been living with a guy at the time and was trying to get pregnant. She even let her fiance call me and cuss me out and threaten me. Found out she was trying to humiliate me because I was so nice and she thought it would be funny to get me to ask her out. Cost me my doctor, and about $20,000. I really want to get some revenge against her. It has taken me two years to find out her last name and where she leaves and her husband's name. Is it wrong if I call her and cuss her out? What if I find outher ways to embar her without letting her know it is me? Sent her husband a letter from a "girl" talking about their affair. Sent her embaring postcards including some to her job and neighbors advertising enlargements and photos. Is this wrong?
