What does this action of hers mean?

hey,kindly give some advice on this incident. There is this girl who stopped and even asked her friends to stop speaking to me,but i just kept cool and didnt do anything of any sort which hurt her.We didnt speak for almost 8 months.But she spoke to me 2 days back.I was cool and spoke to her softly as if nothing happened.when she started speakin to me her face lit up and i just loved that.It appeared that everything was going on well untill i observed her hands,she was kinda playing with it,she must be very nervous speakin to me,but i just maintained my calm.After abt 5 minutes she said that her friend was waiting for her so i bid her good bye in a very pleasant way.After some time i found out that no friend was waiting for her and it was all made up..I was a bit broken.She didnt even bother to text me later.Kindly make some things clear for me.Is it the way the things are appearing to be.
