This Very Smart Girl Is The 'Man' In Our Relationship

I know this is kind of odd and maybe not a lot of girls in nigeria behave manly, however i have seen it a lot. Some girls go for the guys instead of the guys going for girls. Hot guys know exactly what am talking about. They will like to take advantage of you even if you have a girl friend.

Recently I meet one girl in my local bar who works for exxon mobil. Very smart girl but my problem with this girl is that instead of me being the man and trying to impress, it was the opposite and she is planning to move in with me this summer. I am getting "it" but i don't feel confortable in this type of relationship. What do you advice?
