I'm With Who?

A fter 2 weeks of marriage I was alerted by my wife that I had been dating someone before our wedding, the day of, and continually since then...in fact several people. I had no knowledge of the existence of those i was accused of being with, but they seemed to know quite a bit about me. My wife later showed me many sites that apparently we had dated(me and these unknowns) most of which i was not aware of. Stranger yet, as time progressed i started recieving e-mails from these people and i have reason to believe that some may have actually stalked us beyond the internet. After going to movies with my wife they would send messages about what we were wearing, how we looked, and how we walked right by unknowingly. the emails turned threatining and eventually i removed all my known social networking sites because of it, much to the dismay of my wife and friends who think i hate them and won't listen to any other explanation. since then however, the constant messages have seemed to cease, as has my communication with just about anyone...
