I'm sorry that you got scammed, I hope she didn't ruin your future hobbying life! There are a lot of great girls out there.
When I was with my agency, I had seen this Indian guy, called himself Alex, in Chicago. He saw me once and it was all good. Second time, he didn't leave a donation when he left. I thought he left it in the bathroom. My agency tried contacting him, but no answer for days.
Then he scheduled another appointment, said sorry about the last time and that he had simply forgot to leave it. Ok, no problem, the guy was really cool during our session. He sees me a third time, gives me the donation from this and last time- as well as some extra for forgetting last time.
Fourth time, he books a two hour appointment, this time I asked him before he left if he had left the donation. He said yes, in the bathroom. I was completely naked, so I didn't get a chance to run after him when I discovered the donation was not there.
This is a fool me twice scenerio. The agency blacklisted him and contacted some local providers who said it had also happened to them.
I just look at it this way: you can't have the bad without the good. Every situation is an opportunity to grow and be wiser.
