I don't mean to hurt your feelings, but I think you are overanalyzing it. I have been known to do this myself. I believe I am objective here, and I don't think your friend really wants to be friends anymore. If the relationship causes you to feel like a stalker, you are with the wrong friend. Drop contact with her and pursue other things. I think you'll be very glad you did, once some time has gone past. If you need additional help getting over her, I would suggest talking with a professional. Good luck to you...I have been in your shoes.
