As soon as I read the title I had a little laugh. And as most have commented, its a very deluded view, or dangerously naive. The thing is, we are punters, they are WGs. If you want a date, hop on to Tinder or some other dating site. The women we meet on AW or similar have realised they can make money out of spreading their legs. And for us its the convinience of fulfilling our various fantasies with the simple exchange of cash and no (hopefully) commitment after.
But in a way I get what the OP is trying to say. Another way the question could be asked (bear with me here) is: "How can you tell if a WG is infatuated with you".
Now that is more likely to happen. They have a job that could get lonely, punter in and out, different shapes and sizes, different personalities etc. Then a guy comes along that they just connect with. And it could be anything, personality, looks, intellect. A number of things that may just be what she as a woman pictures her perfect guy to be. And then he "treats her well" and maybe comes over again. She might at that point give him signs that he may or may not pick up on. What happens after, I dont know. Depends on the guy. But more than often, she realises he isnt the perfect guy, or he just moves on to another WG to satisfy his urge for punting variety.
I've had situations where WGs have tried to make a relationship happen. I've had free fucks, weekend stays for free, both at theirs and mine. Note WGs, so several. Because I knew they wouldn't last. For many reasons, including the fact that I know for me it wasnt headed anywhere, even if in some cases I had to be a dick to just end it. Last one was actually took me by surprise. about 2 months ago got a response to a RB for a 1 hour outcall. It was a profile I had not come across previously. Pictures were rubbish and profile pretty basic. She simply sent number as well. Normally I would ignore but mailed her and she responded pretty quick. Called her and she sounded pretty friendly as well. We arranged to meet same day. She came over around 5pm. I was pleasantly surprised how pretty she was. We immediately clicked and the following session was pretty amazing. I had no plans for the night, staying in a hotel for work. She was extremely horny and insatiable and the hour had gone by very quickly. I was looking at the time, she wasn't! I had to remind her the hour was up after 15 mins as we had been chatting after the second vigorous round of sex. To my surprise she said she wasn't in a hurry to leave unless I wanted her to go. Well, in summary our 1 hour booking turned to be an overnight and not one penny extra to the amount I had paid for 1 hour! It was an all night fuck fest! I lost count how many times I came, was puffing dust by morning. She just kept coming at me, was all cuddly, telling me a whole lot about her personal life.
Funny thing is her profile disappeared less than a week after. We kept in touch and I've seen her twice since I've been back to her town. Overnights again with me giving her the amount for just for an hour and she deciding to just stay over. I know she has regulars so even without an aw profile does her thing. So do I.
Point is did/does she like me? Maybe. Infatuated? Most probably. For me though it filled up what would have just been a night watching hotel tv and struggling on the whether to have hotel food or order Deliveroo.
