Been there, a few times. First, you haven't said anything about the way she feels about you. Are you just another client to her, or does she think you are special, too?
There are all kinds of girls in this business, just like there are all kinds of girls everywhere else. Some are "emotionally dishonest, manipulative women," some are the sweetest, kindest women you could ever hope to meet. But without exception on the first, and very few on the second, they share two things in common:
1. They fuck men for money.
2. They do it because they need far more money than they could ever earn in any other job they are qualified for.
Assuming that she feels the same way about you that you feel about her, or at least you think there is some potential for that, you need to either be very comfortable with fact #1, or be rich enough to eliminate fact #2. If neither is the case, don't get involved, and try to stay away. Otherwise you are likely to get hurt.
