Heartbreak is painful, I know it and I'm sure the others can relate as well. But I too have to agree as well with their advice. The best thing to do is to just let her go and move on. If she really is meant for you, then she will come back and contact you again.

If in the case that you do decide to pursue her, then I just hope that she is really who she says she is for I myself have encountered several people on chat/IMs who misrepresent themselves. The most recent, being someone I have connected with as well after a month of chat/IMs and over another month of knowing each other through posts at a messageboard. I will not go into the details as you have done. It is a long and painful story that ended in parting as well.

I know how you feel as I have gone through it as well. But I have moved on and it has done me good. I hope you do too and find happiness once again.
