i'm the kinda person who shouldnt even try and give advice on relationships....so dont take me too seriously.
as a girl i could use that as a way to turn someone down politely.. but then again it sounds like she likes you and enjoys spending time with you. i wouldnt try get close to someone i'm trying to "get rid off" anyways.
and... after my last relationship which was totally fd up, i really did need some time for myself and couldnt even think about dating anyone. so.. really..what i think you should do is confront her and ask her out again. i've been turned down a few times lol it was disappointing and broke my heart :P but i know now tht i'd regret more if i didnt even try. give it a shot. you wont "ache" forever. you shouldnt give up.

good luck no matter what you decide to do
