Well, keep your guard up. I'm not saying you are the mark for a long con, but it's quite possible she is seeing some ... err ... opportunities in you.(there was a moment she mentioned the money needed for a passport and I flagged it to myself as a red alert... but it was during a overall discussion about her future, I almost felt bad being to "mean-minded" on that occasion)
I had this same experience once, where a cam model I was a regular with (short version) started communicating with me outside her working hours, only to drop the "I need money for X" bomb after a few months. Maybe she actually liked me, trusted me and did some extrapolating on all the tokens I had dropped on her, and then figuring the begging for money was a safe thing. I don't know, but I cut her off. It was so obvious that I was money manifest to her, or a ticket out of wherever. I have lots of needs, but a russian trophy wife is not one of them (I'm over 50).
If you want to continue visiting camgirls make some ground rules for yourself, or you'll end up in a very bad place.
And if you are still talking like this six months from now and your bank account is intact, come back and tell us. Because in that case you at least made a good internet friend
