girls pls help me ..?

This girl is my college mate At 1st .. without knowing her on the first sight i went and told her that ur looking good, nd after sme days gave her greeting on her birthday in the college ... she returned it with great anger .. and sent a message in fb stating that " I dont like to be your friend or anything else"..after that whenever I cross her in the college she will stare at me .. I also see her .. this went for about 4 months .. after that i sent her a message in fb that .. "I was just an usual thing wat i did for that why you are not talking with me it really hurts me when U stare at me , sorry for each and everything wat i did and 1 more thing even now i want to state that you are the cutest and the prettiest girl in my life " she replied that "I didnt like the way you gave greeting without knowing me .. and dont worry i will talk with you " after that i was asking about her and she as asking about me .. after that i gave request in G talk .. when ever she comes online she will itself initiate the conversation .. but wont talk wit me for more than 10 exchanges .. she will say some xcuses and leave the chat ... unlike before she is not even staring at me or seeing me when i cross her in the college .. now my question is pls tell me why she is not talking properly with me and why she is not seeing me as wat she did before ... does she likes me ?? does beauty matters in this .. ?she very well knows that i love her ...If you love someone else and you find a boy like me crazy on U will you talk with him or ignore him ?
