Gee whiz, your letter wore me out.  Talk about over analyzing a situation.  Man, relax.  It is not all that difficult.  The lady just needs her space.  You two are very young and she is still looking around.  Get out of your head so much.  The sort of over analyzing you are doing will cause you to lose touch with your feelings. Also, there is another word for it and it is "manipulation."   The best you can do in a relationship is to love the other person and if that's not good enough then they have the problem not you.  Move on and find someone ready for love.
