Try being sensitive, helpful and unselfish for a lengthy time period until trust is built. Then, she will see a real person who cares about you and not so much your money.
This has been my experience.
I'm not looking for a best friend but I do accumulate friends and friendships, and there are some women that I'm friendly with who used to do sex work for a living. They don't see me for my money, because none is ever exchanged. And I don't see them as just someone to fuck, b/c in fact I don't fuck them for the most part. But that's me, I've always been friends with people who have had more interesting lives: junkies, whores, dancers, artists, musicians, etc. So much more interesting hanging with them.
The rest of you have no real clue. Especially those of you who start your posts with "These girls..." or "All these providers..." It should be obvious that of course they're NOT all the same, and of course they're not the same from day to day or year to year. As the time goes by, they have ups & downs, successes & failures, changes in tastes and wants and needs. Just like us. Just like the mythical civies. (Civies who are somehow simultaneously not like these whores, but are also still only out for our money and are all bitches and hos anyway.)
And no you don't have to marry them. Just like you don't have to marry your random hook up in a bar or dating app. But you can get to know them and some are worth knowing. Some are way fun to spend time with. And many of them are pretty hot. Some you may even get into their pants by the end of a night out. (And if you bought them dinner or a few drinks and can only think of that as payment for potential services, you need more help & advice than this board can provide. )
