Some of these providers are VERY GOOD at making you feel special and as if you are the only one. In reality, the three who I thought I had that with... turned out to be an illusion.
One--who had claimed to want to hang out as FWB's on our own personal time--never managed to actually follow through on it, going so far as to cancel plans on me three times. One of these times, I had taken the day off from work to help her with a project she had, but... at the last minute... something came up. Something ALWAYS came up, and that was all I needed to know.
Another one who I had genuine feelings of friendship and affection for tried scamming me out of money. I think she was pressured by her BF at the time to do so, but she could have refused to do so. That one was truly sad.
Finally, one that I had deep feelings for and who talked about possibly being together if I could ever leave my long-term live-in GF, semi-ghosted me after she quit the business. I think we are still somewhat friends, but thought we had a closer friendship than what we apparently had. We still follow each other on social media, but I'm pretty sure she would be fine if we never spoke or saw each other ever again.
So what did I learn from all of this? A providers job is to provide a fantasy experience, much like an actor provides an fantasy experience that engrosses you and makes you forget your real life for a short period of time. To think it's anything more than that in 95% of the cases is just evidence that she did an extremely good job of it.
