guy ,
i hope you keep all Ur email and text and report them to the police
get them to send you email direct to you're personal account ( even if you set up 2nd account)
There are basic steps to find the person :
1. Get the email headers, find the IP adress , find them - block them
www.peoplesearchpro.com/journalism/spy/trace.htm/or just forward the email to the police ( don't copy any paste the text ) you need the information attached within the email
all this information can be useful and stop any future people from getting scam
i did this a few year ago , I got a very nice email from NZ police 12 months ago saying that the info i gave them solved a 3 million fraud case
most the people who scam aslo do thing like , Bank scam , drug, abduction
and the 1 phone call or email they send you could be the slip up that put them away
even if they cant catch the person , they will block where the email are send from.
this is the same reason why we now get less spam and pop from places like Russia
