Hey Becurse. The best way to act around women is to be your authentic, normal self.
Don't do ANYTHING because she will like you for it. Let all your actions come from a place of 'what I feel like doing'.
Funny enough, this what makes women really attracted to men.
So if you feel like pulling out her chair, do it. If you particularly like anything about her, compliment it. But don't go over-board with the compliments.
Having a date with her is one thing, getting her attracted to you enough to sleep with you, or become your girlfriend is another.
I wish you luck.
