Martin all the way
I think Mystique is is saying that women are good at being naturally curious about how you're going to provide for the future. You don't have to brag because they enjoy getting that information out of you more than the actual information yourself. It's like a cousin to envy. They want to possess the character that you are but it had better be riddled with enough twists and turns to keep their interest. You can also impress them by being a sharp shooter about your decision making process, this isn't bragging it's just being direct with your intentions. Being bold and being arrogant are very different sides to the same coin.
