ur story is abit similar to mine, juz that for me, she is not so
active, rather the quiet type...
hmm i suggest u to wait, and move on at the same time... thats what
i did last time.. and finally, she gave me a chance... we
relatively close to each other now...
i teach u sth, support her, help her with her problems... let her
feel ur sincerity.. encourage and jia you for her... she can feel
it, i believe.. but meanwhile u have to move on... u have to show
her that u are strong, and not a weak guy.. girls dun like weak
guys.. 
gd luck
