I mean I have/had feelings for her. I have known her about 5 years now. So how do I play it cool when I get the text "Hey when do you want to do the hotel again"?
How do I tell her I'm not interested if its just going to be shitty ass lap dances?
Well the feelings thing...that puts another dynamic into play and alters my advice. There is likely a better chance to win the lottery than fall into a real (meaning both sides forego all others) relationship with a currently providing stripper or a hooker. I would say move on.
When she texts, tell her straight up. No more fucking and sucking, no more hotel and $$$. Although I would probably try to get her to throw a leg one more time for good measure, on the house or just the price of the room. Explain that it would make up for the last few less than desirable meetings and would make you feel less used moving forward...but then hit it and quit it...no moving forward, just don't tell her that until later. I am only suggesting the possible freebie to cover your previous "losses."
Again, plenty of fish in the sea...especially if you are dropping coin to play!
