this is kinda odd but

basically a long term girl i liked (who i am (/ was?) very good friends with made me fess up to her about how i felt. (she had known this for a long time prior) and we were still good friends, messaging everyday for hours, but as soon as i saw her in person she would not look, talk or even face in my direction (we were sitting next to eachother) this is really not like her. afterwards i asked if anything was wrong and she shot it down with “i just hate this class😂” . i’m confused on what to do and if i should try and rectify it
