Yep, I've said it before and I'm sure I'll say it again. These girls are just doing their jobs. This is how they make their living. That doesn't mean that they don't enjoy it (I quite enjoy my job too) or that she doesn't like you--you may be her favourite client, or one of many. Part of their job is to connect with you, and make you feel loved. She is obviously very good at her job.
You probably don't see nearly as many people of the opposite sex as she does, and are opening yourself up emotionally to her. That's fine, that's part of it too, and what makes it special. Enjoy it as a fantasy relationship for a half-hour, or an hour, or whatever. But don't think it's a romance because chances are, it isn't.
