What am i to do?

I am really confused on all these girly messages. So sue me I just don't get them.

To make a long story short, there is a girl in two of my classes, she is pretty cute not completely hot or anything. She is somewhat the loud type and im the quiet type, i just sit back in class. But i party a lot. There was one party yesterday which I invited her to, she said she will check then the other when i asked she said she couldnt cause she had to do something with her sister (dont remember what) so i asked her if she was going to the other parties and she just said to tell her about it then she just walked off. She does say hi whenever she sees me but we never really talk. I am also into photo

i was told by people in my previous school that i was disgustingly ugly. i am pretty skinny (underweight actually, long story) have blonde shagy hair that i still use a bit of gel on. i still have some acne scars left

should i just take this as a hint that I should leave her alone or what?

i would ask her one more time and see how it goes and if that doesn't help then i suggest that you just leave her be....

maybe she likes u as a friend but not as anything more.
