Thanks for all the input once again. I see that I had my own stereotype that was probably off. We have talked, many times, about equality within the relationship, and I can see that point being valid in this case.
One of my concerns was the face issue. By letting her pay, am I losing face in her eyes, as well as her friends and family?
Also, when we get married and she moves to America (I guess I should say if, LOL), I want her to know she can depend on me while she is adapting to life here and trying to find work, etc.
Finally, I hate to see her spend money, because she makes so much less than I do (although I would never, ever say that).
Besides the obvious stereotypes I had in my mind, these are some of the issues that were concerning to me.
Again, I really and truly appreciate everyone's advice here! Thanks very much!!
