If this was a vanilla relationship I would say that you are getting in way too deep, way too fast - can you really love someone in such a short space of time? Do you have friends (lifestyle or vanilla), a job, family? Perhaps you need to pull back a bit and concentrate on your Master as part of your life rather than the be-all and end-all. Dom or not it must be hard to be the repository of someone's entire life especially if he has a hectic business life.
Good luck chick.
