You say you have an overwhelming amount of respect... But somehow that seems to mean something different to you than it does to me. When I have respect towards someone I'm honest with them, keeping something directly relevant to the relationship a secret seems disrespectful to me.
Like, according to what you said so far, it seems like you either reduce/break contact, or you run the risk of having to break contact forcefully once you fall in love and you can't handle it. Both seem to affect her. Keeping that secret doesn't allow her to prepare herself or have any possible agency in the matter. To me, that seems disrespectful.
I think the shaming of sex workers is more of a sexual strategy than one based in wealth. I know Lemmy is (luckily) very anti-capitalist, but I think in this case poor people do the same shaming as rich people.
