Will Amanda ever return, or will i never see the light of day?

is it because now she has no competition that she decides to leave my life? i have not heard from Amanda in over 7 months. i still think about her. i want her to return to my life but i do not know how to keep her in my life.  not only am i not successful in the dating area, but i do not even try. because i know that unless they come to me it is not worth it to come to them.
