This is either real or the author is a brilliant liar. If it's the former, my sincer sympathies go out to her. Many of small facts that the author presented matched quite well with respect to the place here (Michigan). I was bored so I did a bit of searching. There seems to be a person by the exact same name "Sixing, Liu" living in Muscatine, Indiana. I am not gonna post his private info, but if anyone is interested, check out http://maps.yahoo.com and enter his name...there is only one match.
I am totally shocked to hear your story! My greatest sympathy to you in the first place! Such dreg of human being deserves to be severely punished!! At least you have the obligation to let other people know who this so-called 「牛」, or actually劉思行 is !! Not only for you, but also for the rest of the people around him. For other girls/ladies who may fall into his prey in the future!
