Im totally crushing on this girl,Ive been sending signs,but is it possible that she has no clue at all?

First,I gave her a choc.She asked me y[first time we ever talkd].I said simply because I find her cute.The nx day she came to me n apologized becaused she hd to hurry da day b4,n she thnked me for da choc thn we had a real cnversation-whr do u *** from etcetc-.Then I dropped a picture of an angel in her bag wifout her realizing[writen '=) always,cuz u luk even more beautiful when u smile'] Whn she found it later,she send me a text saying thx n she liked it very much[this is hw I gt her numbr].Dats whn we strtd to send texts 2 eother.I thnk Ive bn quite obvious that I lyk her.And she hs reponded positively too.But is it maybe because she ws just being nice?I would walk her home from cl evry chance I gt even when my cles ends way early thn hers.Thrs this 1 tym,she said she hd to hurry so she cldnt stay wif me a bit longer on her way home,but when we arrived at her stop she asked if I wntd to walk around da block,just so we cud spend a lil more tym 2gthr...Im soo cnfused..
