Men should do the calling, at least in the beginning. If you're interested, you'd better call. Remember, you are supposed to do the pursuing. Women who call men regularly are finding that they almost never get the lasting relationships they want. When men don't call, there is a reason. And it's usually that he's interested in someone else or seeing so many people that he doesn't deserve to have a quality woman anyway. So, guys, if you are interested, don't refrain from calling, thinking she'll be jealous. What will most likely happen is that she'll become disinterested. High-caliber women are busy and resourceful. If you don't call her, someone else will!

Whether or not this is fair, it's important to let her know that you are thinking of her no matter how busy you are.
