Very confusing virgo girlHow to deal with it?

well ,i knew a virgo girl ,we are bit close, and im interested in her ,lately she tried to fix me,she was complimentin my look,testing me in some situations and plays !! well we used to laugh with eachother about silly things, and she liked me..as a friend u know but im still interested in her ,we study with eachother , she sits in front of me , and i sit next to a friend .im not that stucky i dont talk to her too much cause im shy

as normal we used to talk to eachother , but now she ignores , when she turn around she doesnt even look at me in the eye,when i meet her at the stairs she ignores me..

i told her sorry ( even if i did nothing to her)she said apologi accepted even if you did nothing to me, but she still ignores me !!

afternoon i ve made a joke,she took it seriously and didnt wanna talk to me again!!i ve changed my seat, cause i was too angry and hurt, even my friend that is next to me always tells her crap and she always laugh(and u guys say that virgos dont like crap -_-')my feelings are hurt and i dont wanna sit behind her anymore!!i know that she plays hard to get but thats just too much how to attract her again , i know how to treat virgos , but this is totally insane ..im really hurt ..should i give her space ?will that work??help me please :/ i ll be thankful
