Two months ago, after posting a picture to my Facebook in which I said I “felt beautiful,” I started getting email messages from someone I didn’t know that were vicious and cruel. I am chubby, and my harasser wanted to tell me, as nastily as possible, that I was deluding myself for thinking I could be beautiful. Not knowing who was writing to me, I made my Facebook profile more private. But recently a friend suggested that I compare the IP addresses of my harasser to the IP addresses of emails from people I know. To my shock, I discovered my harasser has the same IP address as my best friend’s boyfriend, Adam. Adam lives alone, and based on the times the messages were sent I do not believe another person sent those messages from his computer. Adam has always been kind to me, and until my discovery I thought he was my friend. His behavior makes no sense, and I don’t know what to say to him or to my best friend. What should I do?
