Girls, what is going on with her?

She had a huge crush on me in seventh grade. But in eight grade on the second day she saw me and is like "awww hi jeff I really missed you!" and stuff like that. But I see her in my lunch every day 4 and 6 and both days I walk right by her on purpose and she doesn't say anything to me never. She looked back at me going to lunch and she didn't say anything at all but this one kid walks by and she says hi to him! But today I was walking right next to her and shes like hi jeff in a wispering voice and I talked to her a little and then she she kept saying "walk faster Jeff!" Even though we were at the same pace and then I said "By jeff" And then I am throwing something away before cl and there she was and she wispered "Hi jeff" again. And she did this when her freinds werent around. Do you think she still likes me and was waving the green flag and she was really trying to give me hints and thats shes saying, "Jeff I still like you and I want to go out with you." do you think she was too embaressed to talk to me in front of her freinds because they know that she likes me? Do you think she still likes me? Do you think she is just a little afraid to talk to me?
