Does she wants my validation??

I was pursuing my classmate who had a breakup a year ago…she knows that i am interested in her…at first she didn’t showed any interest in me and was just speaking with me as a friend….but now recently she indirectly told her interest in me…she doesn’t initiate any conversation most of the time only i initiate…i then started to reciprocate it… and asked her why she doesn’t show her interest if she is interested in me…she told that she doesn’t proof it and doesn’t show it….i was confused with her answers thats why i again indirectly asked her (in a funny way not in a serious manner)whether she is interested in me or not??….but she then told me she is not interested in me indirectly and that in same funny way….and we had this chats online…in class she acts normal and talks to me and teases me and everything…we also have eye contacts too and now a days its more than before…sometimes we have prolonged eye contacts too she is a funny girl basically and lives only with her group of friends and talks to others if only asked…her friends to know about my feelings towards her as she only told them obviously….they sometimes teases us indirectly….Can anyone help me what’s going on does she needs only validation??
