Fair play to you Tom...a salutary tale, indeed.
There's a lot of cynicism on this board, a lot of it justified.
FWIW, in cases such as these, I think both sides can start to feel 'those' feelings...I don't think the WG is always just thinking of the money in cases like this. And of course, I guess the view from 'the other camp' is that in cases such as these, they might think the guy is always after freebies by fooling a girl into thinking he has feelings for her. It cuts both ways.
I never understand some guys' attitudes towards prostitutes, that they are 'lower than the low' or to be ridiculed, resented and automatically mistrusted. It takes two to Tango: a prostitute is no 'better' or 'worse' than a punter, it's a very evenhanded transaction.
But this just goes to show that meeting a girl for paid sex starts out as a totally synthetic act, and is intended as such, by both parties. But the lines can become blurred and then the heartache starts.
I think what probably is the case though, is that the guy will get more hurt here than the girl. Because the traditional 'roles' have been reversed: normally a guy will be more highly sexed than a girl, and will be checking out other girls - in a relationship it's statistically more likely for a guy to cheat and ultimately leave the girl, leaving her hurt.
In the punter/WG relationship however, the girl is having a lot more sex than the guy and he finds the girl more exclusive than she does him. So if 'a special relationship' develops...2hr bookings turning to overnights, extra services etc (possibly BB)...if it all goes bandy and they cease to meet, the guy is probably left feeling more hurt than the girl. She just goes back to her job, fucking lots of guys and living from it.
It's ultimately a crazy, fucked-up relationship which will burn your fingers very badly if lines are crossed.
