She is still there, I saw her recently.
The good thing about RMT's is that in the vast majority of cases they are not employees of the business. They essentially operate as independent contractors (no benefits,sick days...etc) and most operate they're own business on the side. Polite conversation during a massage can get answers to these questions.
After seeing them a few times at the place they work you can inquire about setting a series of home visits (some work out of their own house, but most will visit you at yours) Keep in mind you have to make this worth their while, either financially or through repeat appointments they can count on.
When they come for home visits tip well, and don't do anything thing silly to make them uncomfortable. No suggestion of "taking things further" should be brought up by you in the first few "at home" sessions.
At this point you have to use your instincts to gauge a) how comfortable they are, and b) where their personal limit is. There is no substitute for being able to read people.
In order to discover their personal limit you need to start talking about subjects that are slightly personal, either to them or you. If they change subject or otherwise show that they are uncomfortable, you're out of luck. Don't push it any further.
If they are comfortable... well, you should be able to finish the last step off with your own style. ;-)
