How do I know if she likes me back? Advice

Re: How do I know if she likes me back? Advice

-Is she stiff when talking with you? sometimes
-Any shying involved? she’s a shy girl, so yes[she told her friend…“he’s shy and so am i”, so I dont know what that means]
-What about your conversations, are they formal all the time?No, rarely are they formal
-Does she ever play with her hair? Um..never payed attention, she wears her hair tied back, she tends to move her legs around alot when sitting on those computer rotating chairs.
-Look at her plams and her shoulders? Are they stiff or not…? Yeah, i think. She doesnt stand up straight sometimes when talking to me.

her friend says she always talks about me [not in THAT way] but nonetheless. Supposedly,…well I told her friend that i like HER. So her friend told me she knew it and that she thinks she likes me back, she’s certain of it because of her actions towards me, and the way she talks about me etc. BUt Im a natural cynic and tend not to believe such things. Im not saying she’s lying but that I dont know…Id love to think she likes me back.
