Sooner rather than later, I would suggest. You are very close to crossing the line that divides ancillary fun associated with paid sex/companionship from a “simple” affair (though no affair is actually simple). In fact, you may have already crossed the line.
How to walk it back? How exposed are you? Does she know your real name? Does she know where you live/been to your house?
In your opinion, what's the criteria for 'crossing' that line?
She has seen my real name before but not sure if she remembers or not. I've had other faves come to my house before but not this one.
