Do You Think What I Did Was Wrong?

I started dating my boyfriend the summer of 2007. He lived with his friend Mike and these two girls lived upstairs. They disrespected me by flirting with him when I would come over. His friend that he lived with started trouble saying he hated me being there all the time so I backed off and would not see MY boyfriend to spare the jerks feelings. He wouldn't even come out of his room to hang out with my boyfriend. He just did it to keep me away from there. He flunked out at the end of that semester so I moved in with my boyfriend. The two girls still lived below us and they would do things to catch his attention. They told my boyfriend that I cheated on him with his old roommate. Now these two girls have always cheated in their relationships. At one point the one girl asked my boyfriend if he thought she was a bad person for cheating. Anyways, so they would lay out and tan in our front yard and wave to him and sit in a baby sized swimming pool in our driveway in bikini's. They said that I was a ***** and that I thought I was better than them. So within the past year I decided to create a fake Facebook profile and use it for payback. I created a fake girl who my boyfriends old roommate pretty much fell in love with and when he went to meet her for their date he got stood up and he was crushed and hasn't dated since. He lives at home with his parents and only talks to a few girls from time to time. Now as for the two girls, I only wanted to damage the one who said that I cheated and always talked to my boyfriend one on one. She just graduated from college and is moving to Columbus officially either today or tomorrow. I added her boyfriend on the fake profile and he started flirting with it saying that the "fake" girl was y and said that he wanted to hook up. He fell for it and I sent the complete conversation between the fake profile and him to HER. Now she just got to Columbus, 4 hours away from him and they have officially broken up. She tried to break me up and I felt that this is what I had to do. Was I wrong?
