Girls, Why is she acting strange around me? Please help me?

There is this girl that i am good friends with. Well she and i are in a class together. She sits next to me and every few minutes she will run her fingers through her hair, fiddle with her pen or paper, touch her face, or put her hands in her lap and like rub them. We our teacher says something funny she looks over at me, laughs, and sometimes says something about it. She never really talks to me though. We hung out b4 school started and we talked alot, but since school started she wont talk to me. She talks to all of her friends and my friends, but never says a word to me. She will sometimes say hi to me in the hall or she will say something about me while i am in the room and laugh about it. When she sits with her legs crossed she has her foot pointing towards me. When we go to conferences and etc. she usually sits next to me

She didnt act this way this summer. She and i spent most of it together and she was more outgoing. She flirted with me alot too, but i was afraid to tell her how i felt cuz she had just gotten out of a relationship. when school started is when she started acting this way. Her ex came crawling back to her and sucked up to her and everything, but she still acts the same way. We had a bonfire one night and she left him to come talk to me about one thing we did this summer. everytime she is with him like at a ball game i catch her looking at me or over in my direction. She has always acted this way around me eventhough we are really good friends. This summer is when we really talked to each other alot and she flirted with me alot. She even held my hand, touched my upper thigh and my chest, but i was afraid to tell her how i felt cuz she had just gotten out of a long relationship. Does she like me, and if so why is she acting this way?

Well, she could like you. But, she's either afraid that YOU don't like HER. Or, that she doesn't want to lose you as a friend if she DOES like you.

She could be in argument with herself on how she feels.

But, that's only a few things.

She's fidgeting. Try to see if she's shaking in any way besides her doing something like playing with her hair. Because, if she's shaking, that's a clue. Or if she's stiff, there's another one.

But, I'm just guessing.
Good luck.

I think she likes you...and because she realised that she`s acting pretty shy now...or it depends on the "thing" you guys did last summer :)

Those are all sihns of her flirting so make the first move i thinkshe likes you we a wierd like that.

She probably likes you or likes to flirt with you if she is an old friend she might like you but not want to ruin it.
