That's the way it goes my brother. Every relationship has one person that is madly in love with the other and one person willing to settle until the next best thing comes around. I've been in both situations before and my last relationship began the same way that yours is now. Over the course of 18 months it completely turned around and reversed itself. I began feeling lethargic about the whole thing and in the end I was in love with her and she had fallen out of love with me. There is no right or wrong answer. You have to take it day by day and do what feels right. As long as you are honest to yourself and honest to her about your feelings you have nothing to lose.
If it is meant to be then you will know it. The pieces will either come together or they will fall apart and you will definately see it when it happens, as long as you have honesty as a backdrop then there is nothing to hide behind. You need to stop and appreciate her feelings for you and communicate well with her. Find out what she sees in you and it may be easier to see it in yourself or to find things that you like in her.
Also don't get so stressed out so fast. It's only been a couple of weeks, how much can you really know or feel about each other anyway? SLOW DOWN your stream of emotions and realize that relationships are built over years and months not weeks and days.
As a sidemark: Pussy has no face. Stop at no limit of lies, deceit and mistrust to get it. (Come on I couldn't lose face sounding all soft like that, could I?) If all else fails just whip it out and go UGGHHHHHHHHH! Some girls like to be slapped in the face with it while they're sleeping. YEAH
