I can tell you that we are from two different cultures and she is very traditional. I am quite traditional myself. She is more shy and reserved than any other girl I have dated or been with. The plans are usually initiated by me, and I find that she doesn't often initiate phone calls. She always comes out, never turns down (unless for family emergency, or close friend or relative visiting town).
Of course, the way things work in this culture, we are trained to believe that a girl that initiates phone calls and text messages is interested in us. Yet, we are still expected to make first moves in asking for phone numbers and dates (same as her culture from what I know). She very rarely initiates phone or text conversations.
Perhaps, she is making things as easy as she knows how to and I may not be seeing that way because of my experience with same cultured women.
