What's really funny is that right below this thread when I started writing this was the one complaining about WG's and their secret contempt for punters
As always in life, it seems humans go in all directions. I found myself nodding along to this part of the conversation:
"There is genuine affection there and I have a similar vibe with my long standing clients. So it's not completely detached but it's not romantic either, if that makes sense?"
I've never had an EAS with a WG, but there've definitely been SPs I've had that sort of understanding OP is talking about above with in the past; it was always just sex for money, but while the circumstances worked for both of us it was definitely a great mutual beneficial thing; relaxing rather than competitive or mechanical (who will screw who more appointments I call those), I was usually comfortable enough to nick a fag off them (a lot of good WGs occasionally smoke; I have a theory that the women who are on the game partially because they like sex like to live more dangerously in other areas too).
Several other OP posts make it sound like this lady has fallen rather hard, which suggests letting her down gently isn't an option. Such situations tend to end with slogans we are all familiar with ("Men are just filthy pigs/women are all whores" etc etc) when someone gets kicked right in the feelz. Personally I'd text from a distance saying I couldn't see the lady anymore and if necessary make up some face-saving bullshit (I can't see you again, I'm getting feelings for you but I'm married with kids blah blah blah). Preferably something that salves the ego while being hard to disprove (like, don't say you've not got kids if you really don't and she knows where you live lol).
OTOH, playing with the lady's feelings by using her for sex as long as you can... well, I won't condemn it, but I will say you must like living dangerously to try it. A woman whose romantic feelings are toyed with like that is likely to react the same way a man who has found himself led on with the false promise of sex/love by some bint who uses him to cry on his shoulder and spend his money, before bunking off with a hunk (i.e. not well!). Frankly I'd rather try swingers and sugar babes than shag an SP who had EAS for me; the only way something like could work was if you were both single, and were clear you were both going to keep shagging other people.
