The only thing is, this has been going on with her profile since March and I'm surprised she hasn't gotten in touch with her regular clients to explain this or even simply say that she is retiring. That's why I was hoping you might be able to contact her and sort out all the speculation and confusion that's going on here. I'm sure a lot of guys would have appreciated that.
Dude, don't stress about it. This is a good reminder that these are business transactions, these girls fuck men in return for being paid cash, it's all part of a business. Owing to it's very nature, said business is a bit shady and a bit under the radar, you rarely get a real name or personal phone number - the fact is, a working girl can simply decide to pack it in and no-one in the world will know anything about it.
You do hope personally that a really good girl would get in touch with regulars and clients she got on well with (I counted myself as one, I met her six times in under a year, and our last communications were friendly and upbeat as ever), just to show them respect as human beings, but she really doesn't have to if she doesn't want to.
The upside of all this is that you get to fuck lots of different girls with no strings attached, and occasionally you find a really good one. The downside is when your favourite girl disappears, you don't know about it until stuff like this happens, and you never know the reason why. And very few ever get to be Richard Gere at the end of Pretty Woman and ride off with their dream escort girl into the sunset, so I'm inclined to believe Raylondoner when he says he's as much in the dark as everyone else.
On a human level, I hope the young lady is ok and well, but I doubt I'll ever know for certain. I just have to accept it and find my next favourite.
