Oof, that is brutal. Sorry to hear.
Similar happened to me however I had spoken to the person for 2 weeks before meeting. I went to the place, they were very active and talking to me until I got there (though this place was public), said they were almost there. 30 minutes of hanging around and then Read more… they blocked me on here and via messages and that was that. I only had traveled 40 mins to the location but still.
it is a strange thing for sure. Makes you feel quite vulnerable. There was no reason to think they weren't interested or real. One day is perhaps not enough, and for sure like others say - a public place should be your first thought. Even guys should be careful, I am a big guy but what if there isn't just one person meeting up when you expect there to be. You just don't know.

On the contrary to your thoughts, I have had no trauma that helped swerve me toward being dominant. A friend at University introduced me to what she and her husband did through conversation and jest and the concept of subs giving up control to their doms was intriguing to say the least.
So there Read more… may well be cases where people have assumed a dom or sub role due to circumstance, but I don't feel it is fair to suggest it is purely as a result of a negative experience.
I know that it is very common for those who by day are in a position of power, have a higher chance of being submissive in the bedroom sense as they find it refreshing to hand that control over to somebody else.
You are right though, it is an interesting topic trying to understand why people choose the path they do. Good topic
