One of the providers that I have been seeing on and off is a finance director (confirmed by finding her linkedin profile) for a well-known company. I honestly don't have a grasp of her motivations, other than her having a love of travel which isn't particularly different from most young women. She is unmarried, sharing an apartment with roommates, and is not the type to flaunt $500 purses or Louboutins. I suspect that at some level she does enjoy providing and just likes having extra money even if she's already commanding a nice six figure salary.
