i don;t know him at all, but i just googled him and discovered that hes given me a different name, different age and that he has another email account active where he lists his interests as being erotic movies!
RUN! If you were my daughter I would file a report with the police and tell you I had done so, so they would know where to start looking when you disappeared. I would advise you to tell him to get lost and if he contacted you again, to get a restraining order. There is a reason why he is using different names, ages and e-mail accounts. This is a seriously bad sign.
Yes, this is harsh. I've been down this road. Five years after she broke up with him my daughter still can't have a facebook page because her ex-boyfriend is still looking for her. Some men are creeps and need to be avoided.
On a more long term note, I would suggest getting in therapy, or perhaps a support group. One of the things the Borg does very well is turn out individuals who are incapable of functioning outside the confines of the cult. You need to move beyond that.
