Dating in Indian culture is nothing more than fooling around. There's nothing serious about it at all. The only exception is if the relationship is Indian to Indian. That means there could be a greater likelihood of success. The odds of an Indian man marrying a white woman are very low.

An Indian man marrying a white woman is culturally-speaking "not suitable/acceptable" on multiple levels. White women are not born and "bred" for entering and nurturing the complex Indian culture, traditions, and customs. They are in the mindset of nuclear families. Indian culture, at its heart, is about nurturing and supporting complex joint family relationships.

White women are not going to become submissive. This would be interpreted as a weakness according to Western culture.
