I think it's definitely a maturity thing. Girls want to be taken care of. Once we cross over into being a woman we know we can take care of ourselves, don't have to prove anything to any man. A man is not there to take care of us, he's there because he completes you. It's not his job to take care of you, and make you happy. It's nice to have romantic surprises like flowers and such, things that are not a necessity but a way to show affection. But don't EXPECT a man to do anything except be faithful and truthful if he is the one for you.

Edit: Men want to care for their woman, and provide for her....but a woman should not expect it out of him.
