How many times have we heard: I've fallen in love with an escort girl, I don't know what to do? I'd like to start by saying that this is normal, an escort's job is to be kind, charming and GF. So if you have a crush on a girl, she's done her job well.
If she doesn't tell you she's in love, that's easy. Either you're strong enough to continue the paid relationship (but don't get any ideas, because there's always the risk of being taken for a ride), or what seems healthier, you stop contact and go meet and enjoy yourself with another girl.
We've often heard: I don't pay to have sex anymore! That may be true, but who decides when to have sex, and do you pay for her vacations, her apartment, her shopping? Do you buy her gifts? If you spend more money with her than in a "traditional" couple and you don't pay to sleep with her, maybe you're paying anyway, and she knows it... Some men, especially lovers, are more generous if they don't have to pay. Some girls are highly intelligent and specialists in human nature.
Once again, it's possible, but whether it's true or not, she'll tell you and if I mention it here, it's because it's not the first time it's happened... You're the only one who can judge the situation and know what risks you're prepared to take. But remember, if a love situation is always complicated and risky, the one you're in is even more so.
Maybe this is your case... Savior syndrome is a psychological "disorder" that consists of over-empathy for other people's problems. If you want to help her out and are prepared to make a lot of sacrifices, you might want to read up on the subject.
Always be wary if you fall in love with a prostitute, because the situation is flawed from the start and it's a perilous one. Stop the relationship for a while and wait to see what happens, or accept the situation as it is, knowing that you'll suffer heartache... But who knows, love can't be controlled...
